News from our previous
events in 2004 & 2003
This
page of our website is kept on line for you to continue to
enjoy the stories and accomplishments of our organization
since its inception:
December
2004--Sea & Learn is proud to announce the winning of another
international award. Presented by Unterwasser
Magazine and VDST, German Federation of Scuba Diving, Sea
& Learn on Saba won 2nd prize for its scientific work with
Project Seahorse.
Sea
& Learn's Second Year Is a Grand Success. More
than double the amount of experts entertained and enlightened
more than double the amount of attendees. Saba School
children from ages 5-16 had bi-weekly presentations in
subjects ranging from muck diving to cave exploration.
The Ranger/Scout Club, associated with the Saba National
Marine Park, tripled enrollment during the month-long
event. The intrigued youngsters participated in weekly
hands-on field projects from cactus planting and lizard
surveys to seahorse identification.
In
addition to working with Saba's school children, this year Sea
& Learn is proud to report the inclusion of students from
the neighboring island of St. Maarten and St. Martin.
Students made a day trip on The Edge ferry. The visiting
islanders first enjoyed a presentation at the Saba Marine Park
multi-media center. They were next taken by buses to
Windwardside to conduct a field project after having
lunch. Each student personally donated $1 to Saba's
Marine Park.
Come
join the fun! Plan to visit Saba for an upcoming event
or make plans for October 2005. Whether your dream is to
capture underwater images or to understand the fragility of
our turtle population, Sea & Learn offers something for
everyone.
There's
no reason you can't participate as well. Remember, Sea
& Learn on Saba is fun, it's free and it's for
everyone. For more information or a reservation,

SABA—International
shark expert and research biologist Dr. Mark Marks lectured
Monday evening to a crowd of about 75 at the Brigadoon
restaurant in Windwardside.
Marks’
talk was accompanied by close ups of his personal encounters
with White sharks, all taken in open water without the
protection of a cage. Many of the photos were taken off Dyer
Island, South Africa, where Marks conducted his studies in the
behavioral ecology of the White Shark over an eight-year
period. Although the white shark is relatively rare, it is
wide ranging in all seas in both hemispheres.
Marks
reminded his audience that there are more than 500 species of
shark or rays, basically unchanged over seven million years.
He compared the intelligence of the shark with that of a
domesticated household pet. “These are the world’s largest
carnivores at more than 21 meters and are highly self aware,”
Marks said. Since these sharks are warm blooded, they can move
very quickly and unpredictably, which allows them to track and
capture other intelligent species, such as dolphins.
While
undertaking shark research off Guadalupe Island in Mexico,
Marks noted 66 different shark behaviors and was able to
observe the shark’s social interactions and possible
cooperative hunting. He noted that the shark would sometimes
attack, but not necessarily kill its prey, or again kill it,
but not completely devour it. “The simple answer to this is
that they have had their fill, and it’s easy for them to
come by the next meal,” Marks explained.
Marks
will meet with the children’s Scout group on Wednesday
afternoon, and will give another public lecture on Friday
evening. During the week, he will be available to resident and
tourist divers as this week’s Sea and Learn nature expert in
residence.

Hanlon
SABA
—Marine biologist and octopus expert Dr. Roger Hanlon used
local and visiting divers for his octopus research on
Saba
’s reefs last week.
Hanlon,
who is senior scientist at the Woods Hole Marine Biological
Laboratory, gave two public lectures during his week on
Saba
, his first time to the island. His research is sponsored by
the Sea and Learn
Foundation through an AMFO grant.
The purpose of the research was to document camouflage
behaviors of octopus and flounders in shallow water. Hanlon
made over a dozen dives, with each dive lasting almost two
hours in the shallow environment of Tent Reef to the west of
Fort
Bay
and harbor mooring sites to the east.
He
showed guests Saturday night at the Swinging Doors sensational
footage of a small defilippi octopus quickly burying itself
completely in the sand in the mooring area. He said the
segment was good enough to be shown on television nature show.
Hanlon
found four species of diurnal octopuses. One sighting caused
special excitement. The octopus showed “mimic” behavior,
as it tried to get away with flounder-like movements. Hanlon
said that more documentation would be necessary, such as a
video. If it were true mimic behavior, it would be the first
observation of this outside Pacific diving sites.
Hanlon
has asked local dive masters to keep track of octopus
sightings, observe and document behaviors, and to take videos
whenever possible. He plans to return to
Saba
next near to follow up on the study.
Experts
explore Paris Hill caves

SABA—Suspended
from a rope, with all gear and helmet removed to fit into the
narrow passage, Leda Brewer was pulled back to safety from her
attempt to come to the bottom of a Paris Hill cave. Any
further descent, she determined, was decidedly unwise.
LOCATION
Brewer and two cave experts recently explored to their depths
two Paris Hill caves as part of the Sea and Learn Nature
program. Paris Hill is the base of a rocky formation above the
cable office in The Bottom. The formation is known as “the
whale” since it has that appearance from The Road. From the
seaside, the “tail” of the whale resembles a triangular
tent and gave Tent Reef its name. According to locals,
mariners used the tent as a navigational aid since its aspect
is so distinctive from a distance.
The
caving expedition actually started more than a year ago, when
local dive shop Sea Saba had the idea to take advantage of
Saba’s caves and cliff faces an alternative terrestrial
sport: rock climbing/cave exploration. Brewer, a dive
instructor with Sea Saba, was a seasoned rock climber and
first explored one of the caves a year ago. She was anxious to
complete her voyage to the bowels of the island, but expert
cavers were necessary for a save exploration.
The
experts arrived in the form of Jeff Bozanic, underwater cave
diving specialist and Steve Ormeroid, who is Administrative VP
of the American Speleological Society. The men have worked
together for 20 years on cave diving projects in many parts of
the world. The cave exploration was part of the Field Study
portion of the Sea and Learn experience.
UP
THE HILL
The effort was community wide: interested locals provided a
sunrise “sherpa” service and carried expedition materials
up the hill on a new path recently constructed by the Saba
Conservation Foundation. The team of three had considerable
gear, including ropes, helmets, carabineers, specialized
climbing apparatuses, and food/water. Tents for an overnight
at the end of a 14-hour day were also part of the matériel.
A
core team was posted at the mouth of the cave in case a rescue
operation was needed. At 8am, the trio entered the first cave.
It went down about 150 feet and most of it was a “climb
down.”
The
second cave was more challenging with a 300-foot descent, and
several vertical drops, requiring the use of the specialized
equipment. Brewer said the caves were totally dark, lit only
by helmet lights and an occasional photoflash.
The
team took measurements of the length of the caves by a rope
knotted every 10 feet. A compass gave direction, and an
inclinometer indicated depth. These measurements resulted in
rudimentary maps of both caves.
Bozanic
was expecting and hoping to find that the caves ended in
water, since that is his specialty. However, both caves are
actually granite fissures; full of unstable “talus” or
debris in some spots, and they narrowed and petered out.
As
the smallest team member, Brewer doffed all equipment
including helmut to explore cave 2 as far as possible. She
confirmed that she felt fresh air on her face at the lowest
point in the cave – about 300 feet from the entrance – but
passage was too narrow to continue. She was also out of
earshot, and realized that any call for help would go
unheeded. The passage was so narrow that she was unable to
pull herself out, but was hauled out on ropes by her
companions.
LOCAL
LEGEND PUT TO REST
Old-timer stories have it that three children disappeared into
the caves, and that a chicken had flown through the cave and
was later found at sea. However, the only signs of life found
by the team were a few old goat bones and graffiti from 2001
scrawled on a rock surface.
The
crew gave their report, illustrated by cave slides, to a
capacity audience at the Sea and Learn evening lecture series.
As part of the Sea and Learn school program, Brewer took her
climbing gear to St. Johns schools and demonstrated her
equipment. Standing as a patient model, student Peter Johnson
was soon kitted out in the heavy gear and helmet sported by
the well-dressed speleologist.
The
students were interested in this unique exploration of the
island, and cautioned that it is a dangerous sport and needs
proper guidance and experience.
Project
Seahorse launched on Saba

SABA—The
Saba National Marine Park has been chosen as the first
location in the Caribbean for a pilot study under “Project
Seahorse.”
Project
Seahorse is an international and interdisciplinary marine
conservation organization, working in Australia, Canada, Hong
Kong, Philippines, Portugal, U.K., and U.S.A., under the
auspices of The Zoological Society of London and other
international conservation organizations
British
marine biologist Alex Cliffe, who is Senior Aquarist at the
London Zoo, conducted four field surveys and located four “long
snouted” seahorses at mooring sites off Fort Bay pier during
his tour as guest lecturer at the Saba Sea and Learn Nature
Series.
Volunteer
lay scientists undertook exploratory scuba dives and recorded
on special underwater paper, details of the animals found,
including location, sex, size, color, etc. It is not unusual
to find seahorses in the Marine Park, but this is the first
time sightings have been officially recorded. Local dive
masters/instructors will continue the work of monitoring the
Saba seahorse population in the pilot study, and will forward
their results to Cliffe.
Cliffe
said that seahorses are territorial, usually remaining in an
area about the size of a normal living room. They live for
about seven years. One unusual feature is that the males carry
the fertilized eggs in a pouch, and give birth to
approximately 300 young at a time.
The
seahorse family (Syngnathidae) has been on Appendix II
(threatened species) of the Convention for International Trade
in Endangered Species (CITES) since May of this year. Cliffe
said that this measure has already been affective: British
customs officials have made several confiscations of
unauthorized shipments of live seahorses.
Cliffe
said that harvesting seahorses for use in traditional Chinese
medicine is a multi-billion dollar business in the Far East.
Since fisherman have themselves realized that the seahorse
population is dwindling and thus threatening their livelihood,
they are anxious to put pregnant males in a special underwater
cage where they stay until the young are born and replenish
stock. Project seahorse is active in the Philippines and has
successfully trained the local population in these pioneering
conservation efforts.
Sea
and Learn hosts dolphin expert

SABA—Dr.
Naomi Rose, sea mammal expert from the animal advocacy group
Humane Society International, gave four talks during her
two-day stay on Saba, at the invitation of the Sea and Learn
Nature program.
Rose
said her first contact with the Netherlands Antilles had come
from Saba resident Angelika Hartleib of Saba, who was
concerned about the proposal to create a “Swim with the
Dolphins” feature on St. Maarten. Concerns soon reached
critical mass, with a vigorous correspondence between Rose,
her charitable organization, and concerned citizens on both
islands, and led to her trip to the Windward Islands.
She
first stopped on St. Maarten, where she gave four
presentations, two radio talks, and several newspaper
interviews. On her two days on Saba, Rose spoke to three
school children groups and gave an evening Sea and Learn
Lecture. She said she would welcome the opportunity to speak
to government officials about the project, and would return if
an appointment could be set up.
There
are about 15 dolphins facilities in the Caribbean with a dozen
more on the drawing board. Rose said the facts do not bear out
any benefits to this type of captivity for dolphins. On the
contrary, life expectation and mortality are much higher.
She
said there are two areas where dolphins are captured: the
Solomon Islands and Cuba. Regardless, dolphins are protected
worldwide under the Convention for International Trade in
Endangered Species (CITES), which requires certain
documentation attesting that exported mammals are a “non-detrimental
finding.” Rose said that there is no scientific information
that can attest to this
There
is, however, a great deal of information regarding the
negative aspects of keeping dolphins in captivity. Rose
recommended substitute activities such as interactive media,
which gave a very good idea of how these animals behave. “Seeing
them in a small pen is not true to life,” she said. She
added there is no spin off value since visitors to such
facilities are entertained, but not changed to be more animal
friendly or ecologically aware
Underwater
drawing launched at Sea and Learn

Saba—Why would you want to draw underwater, is
the first question that springs to mind, when confronted with
a strange apparatus called an “aquaSketch.”
Mark
Hagen, inventor and artist, is quick to answer: “The
immediacy and elusiveness of the artistic first impression!”
For him there is no doubt that sketching impressions on site,
and not from an underwater “reference photograph,” is
hugely important to the creative process.
Hagen’s
answer is a devise that looks somewhat like a child’s “etch-a-sketch”
toy, but is vastly more high tech. The patent is pending on
the product, which had its debut during the month-long Sea and
Learn event on Saba.
The
completely submersible aquaSketch is a plastic frame with a
strip of Mylar paper stretched between two rollers. It can
contain up to 10 feet of paper, which is advanced as the
artist begins each new 8.5x11-inch sketch. The frame is a
bright florescent yellow acrylic, making it easy to locate if
dropped, however, the neutrally buoyant device will not stray
far under water.
A
pullout drawer has a graphite pencil, an eraser, a sharpener,
and special French oil and wax crayons, which hook onto the
palette with Velcro. Hagen said that colors underwater are
tricky, even at 30-40feet, as the water absorbs colors. It
takes a bit of practice to pick up the appropriate crayon.
Hagen
brought two versions of the acquaSketch to Saba: a wrist
model, which dive masters enjoyed as they fired off quick
messages to their divers, and the sketch model for budding
underwater artists. Still in the pipeline is an “in-between”
model, good for text or drawing, also with a drawer for
accessories.
Hagen
first met with his students, who had enrolled in the Sea and
Learn event. After a quick class in drawing – some of the
students were totally untrained – the group went out the
next day on the dive boat. After quick onboard instructions at
the Ladder Labyrinth dive site, everyone got into the water,
was handed their sketchpad, and descended to 40 feet.
Hagen
was the last one in the water. “Everyone got to work
furiously, as soon as they made the sandy bottom,” marveled
Hagen. After the dive, the next step was to take the drawings
and run them through the scanner at the Peanut Gallery. Class
members then took this copy and colored and revised the
original impression, which was displayed at a public reception
later that day.
Hagen,
from New York, is an enthusiastic scuba diver and
environmentalist, and donates 5% of all proceeds from the sale
of his marine work to coral reef protection organizations. The
acquaSketch is manufactured in New York and sells there for
about $350.
Nice
timing!
Turtles Nest at Cove Bay
While Sea & Learn Turtle Expert on Saba

Kooistra, Saba National Marine Park
SABA—Turtle nests were discovered this week at Cove Bay
beach. Marine Park Manager David Kooistra took immediate
action to cordon off the area to keep the nests out of harms
way. Divers in the Saba Marine Park commonly see turtles while
snorkeling or on scuba, but nesting has become less common.
Turtle
tracks were spotted from the airport by Vincent Hassell,
assistant airport manager, who called Sue Hurrell, a Saba
Marine Park volunteer. Hurrell said that there were tracks all
up and down the beach, but it was impossible to tell how many
turtles had come ashore, but they located about seven possible
nests.
Puerto
Rican turtle expert Dr. Pedro Rivera, on Saba for the
month-long Sea and Learn project, visited the site and said
that the nests were probably made by Hawksbill turtles, since
it is their mating season. The turtle is on the endangered
species list, and only about 1% of the offspring survive to
adulthood.
It
is important to leave the nests undisturbed, since the eggs
are normally laid in a hole more than two-feet deep. Rivera
speculated that the turtles had in fact accomplished their
task and laid eggs, given the amount of energy spent in coming
ashore through the rocky debris and digging the pits.
There
are usually more than 100 eggs in each clutch. Rivera said the
turtles would normally return in 10-12 days to lay more eggs,
and would repeat this behavior several times during the mating
season.
A
resident of Hell’s Gate was not surprised, and recalled
turtles nesting in Cove Bay and Spring Bay in years past.
Large turtles can often been seen in both bays from as far
away as the curve in front of the Hell’s Gate Catholic
Church at an altitude of about 1,300 feet.
Both
areas had more sand in the past, Sabans recalled. Cove Bay now
has arc lights near the recreational pavilion, which are on
all through the night. Rivera proposed changing these to low
pressure sodium, since the bright mercury vapor light can
confuse the turtles.
