AusTurtle
Inc
is
a
major
supporter
of
sea
turtle
research
at
Bare
Sand
Island,
Northern
Territory.
A large
population of flatback sea turtles nest at Bare Sand
Island during the winter months. During this time,
researchers and volunteers gather data on the nesting
turtles to estimate population size, monitor abundance
over time and to determine any threats to survival.
This research has been running since 1996 and has
identified an important nesting population of flatback
sea turtles. Funding for the research has always been
very restricted creating limitations to data
collection and the length of the field season. With
increasing support from AusTurtle over the next 5
years, it is hoped that research will be able to be
expanded to include electronic tagging of nesting
turtles, satellite tracking of nesting turtles and
undertaking extensive temperature studies on the nests
in situ. With this additional support it will create
an ideal work environment for student projects,
further enhancing our knowledge of the species and the
research undertaken.
The
waters around Bare Sand Island support significant
numbers of foraging green and hawksbill turtles. Both
species are vulnerable to extinction under Australian
classification (EPBC Act 1999). Green turtles are
internationally classified as endangered and hawksbill
turtles are critically endangered internationally
(IUCN Red List). Annually researchers monitor green
and hawksbill turtle populations by capture of turtles
while they are feeding on the reef. This research will
provide population estimates, relative species
abundance and identify threats.
About the project
Charles Darwin University in Darwin,
Australia has conducted a sea turtle research
project to Bare Sand Island since 1989. This project
is a scientific study to examine the biology and
ecology of nesting and foraging sea turtles. This
will help with sea turtle conservation regionally,
nationally and internationally.
The project is run by Michael Guinea of
Charles Darwin University, Darwin (contact details
below).
Location
Bare
Sand Island is situated at the end of a chain of
islands in northern Fog Bay, about 50 km west of
Darwin. The island is approximately 1.8 km in
circumference. Bare Sand Island sits upon a rocky
reef, and as the name suggests is almost all sand with
very little vegetation and almost no shade.
Environment
Bare Sand Island is mostly sand and
consists of low dunes sparsely vegetated with
grasses and herbs. One tree grows on the island but
it is unsuitable for shade as it is a sacred site.
The island is 1.8 km in circumference and takes
about 40 min to walk around.
The region is subject to a large tidal
range (up to 8 m) and the island is therefore
subject to strong currents. Strong winds can occur
in the area and this makes camping uncomfortable in
the sandy conditions.
The nearest settlement is a house on Dum in
Mirrie Island (over 10 km away). Otherwise the
research camping is fairly isolated with the next
community over 20 km to the south.
Research activities
Nesting Flatback Sea Turtles -
Activities will be conducted at night and early
morning and will include checking the beach for
tracks, tagging and measuring adult females,
counting and measuring eggs.
Foraging Green and Hawksbill Sea Turtles
-
Activities may be conducted during the day and can
include catching juvenile turtles on the reef flat
using nets and by hand, tagging and measuring all
turtles, helping will specific studies on blood
chemistry, diet analysis and movements (using tracking
equipment).
Wildlife Observations -
Other interesting fauna visit the island and its
surrounding waters. These are opportunistically
studied. They include sea and shore birds, dolphins
and dugongs.
Dates
Update
on trips:
Volunteers are required for the 2012
research expeditions between 11 June and 30 July 2012.
There are seven separate research trips. There are
positions for eight volunteers on each trip. There is
a cost for each trip to cover food and transport
expenses. The advantages of staying for two weeks
include: developing a synergy with the island, the
tides and the turtles; having greater participation in
collecting and collating data; enjoying the company of
other volunteers for even longer.
Costs, Registration and
Pre-payment
It is necessary to register your intention to fill a
volunteer position in the trips. This can be done by
checking the vacancies below and emailing your intention
to Michael Guinea (contact details below). A
pre-payment deposit of $50.00 will ensure that your
registration is confirmed and your name will appear
below in the appropriate position for the nominated
trip. The balance of your payment should be made on
arrival in Darwin and before the trip. If you cancel
your registration your pre-payment deposit will be used
to support the sea turtle research conducted on Bare
Sand Island by AusTurtle Inc and acknowledged on this
web site.
The costs for 2012
Full time students = $25.00 per day (i.e. 7 days for
$175.00 or 14 days for $350.00 including AusTurtle Inc
membership).
Non-students but AusTurtle
Inc members = $30.00 per day (i.e. 7 days for
$210.00 or 14 days for $420.00).
Members of corporations = $50.00 per day (i.e. 7 days
for $350.00 or 14 days for $700.00).
A transport surcharge will be
required for shorter trips to cover the cost of
additional boat charges. This will be done in
consultation with the boat operator.
Included in the cost are the
following:
Transport within Darwin to shop for provisions.
Vehicle and boat transfer to and from Bare Sand
Island
Food and accommodation on Bare Sand Island
Not included are:
Food and accommodation in Darwin prior to and
after the trip to Bare Sand Island.
Transport to and from the Airport / Railway
station or Transit centre in Darwin.
Personal Insurance – volunteers are expected to
have their own personal travel and health insurance.
Personal expenses.

These expeditions are open
to anyone. Interested volunteers should complete a
volunteer application form and contact Michael
Guinea at Charles Darwin University on (08) 8946
6707.
All volunteers will be required to fill in
an application form.
What to expect
This is a fun trip but requires hard
work and long hours working under difficult
conditions. Volunteers will help with all research
activities during the expeditions. The island
consists of very fine sand that gets everywhere when
conditions are windy. It is difficult to keep it out
of cloths, bags, tents etc.
There is a composting toilet and saltwater
is used for bathing, dish and laundry washing.
Freshwater is reserved for drinking and cooking. Food
is basic consisting of meats and breads with plenty of
fresh fruit and vegetables. Meals are prepared fresh
daily using fresh ingredients. Specialised food
requirements are catered for providing sufficient
notice is provided on your application form. All
volunteers will be required to participate in general
camp duties including camp setup and maintenance and
food preparation. The main camp will consist of a main
tent/structure to store food and general gear. During
the day shade is provided by a geodesic dome erected
as a communal area.
What to bring
Remember it will be hot during the day and
cold at night, there is limited shade and fine sand
will get everywhere.
General - Hat, sunglasses, long sleeved
shirt for sun protection, long sleeved shirt and
pants to get wet, dive boots or old runners to get
wet, water proof sunscreen or zinc cream, pull-over
of jumper, personal toiletries, talcum powder,
moisturiser, shampoo and conditioner, swimmers,
camera, sleeping bag, water bottle, torch or head
spotlight, fishing gear.
