Satellite tracking conducted to study migration and foraging habitat of sea turtle nest on our coast. Satellite Tracking involves attaching on the sea turtle shell a Platform Terminal Transmitter (PTT) and getting the transmission data from ARGOS Satellite. Te PTT send message to satellite each time the turtle comes to the surface to breathe and the analyzed data sent to MLA researcher via satellite regarding the location of the tracked turtle. MLA attached total 13 PTT satellite tags on Olive ridley at St. Martin Island, Teknaf-Cox’s Bazar beach, Sonadia and at oﬀshore location near Dholghata beach.
ransmitters attached on the carapace with special epoxy glue. After switched on, transmitter started transmit signal of its position to one of the six orbiting satellite called ARGOS at a preset time interval. Tis transmitter helped reveal location data, SST (Sea Surface Temperature), for many days. Tis data derived from ARGOS ground station and are sent to MLA program account. Te International Sea Turtle Society (ISTS) helped to track the turtle through its web site based program STAT (Satellite Tracking
& Analysis Tools) to get daily locations. Widely used references for sea turtle tracking are “Blumenthal et al 2006, Broderick et a l 2007; Godley et al 2002; Hawkes et al 2011; Rees et al 2010”.
SEA TURTLE IN THE SOUTH ASIAN REGION :
Five species of sea turtle occur in this region. Tese include Olive ridley, green turtle, Loggerhead turtle,Hawksbill turtle and leatherback turtle. Country wise nesting rookeries and species diversity mentioned below:
Bangladesh: Current nesting species is Olive ridley and Green turtle; 1000+nests of Olive ridley per season
along coasts of Bangladesh. Only 40-50 nests of Green turtle laid per season and nesting spots are widely
fragmented. Hawksbill turtle last nesting recorded during 1998 at St. Martin Island, only nesting spot
recorded for hawksbill. 250-300 kms are suitable for nesting out of 710 kms of total coastline in Bangladesh;
Sonadia is the best nesting site. Tere was no dead or alive record of Loggerhead. Nesting Beach: St. Martin
Island, Cox Bazar-Teknaf Peninsula, Sonadia Island, Laldia Island, Dhalghata Beach, Kutubdia, Sonar Char,
Kuakata Beach and Sundarban forest coast.
n Hawksbills are found in the Kerala, Lakshadweep islands, Andaman islands, and few beaches in the
Nicobar islands such as Indira Point at the southern tip of Great Nicobar, also in Sri Lanka.
n Green Turtle nest in Pakistan, Sindh Prodesh, Karala, Guzrat, Andan & Nicobar of India, Tamee Hla,
Ngaputaw, Khone Gyi, Wargone, Maydarai, Ngaputaw of Myanmar and in Southern Sri Lanka.
n Olive ridley nest all Indian state coast including Andaman Nicobar and Lakshadweep Islands, Pakistan,
Tamee Hla, Ngaputaw, Bogalay of Myanmar, Sri Lanka. Gahirmatha located in the Bhitarkanika
Wildlife Sanctuary India, supports perhaps the largest nesting population with an average of 398,000
n Loggerheads are not known to nest in India, nests in Sri Lanka and the Gulf of Mannar., Te species
record in Myanmar mentioned in previous research and there is also confusion from local researcher
about the identifcation.
