The Department of Environment and Conservation monitor marine turtles in Western Australia through various programs.

This long-standing marine turtle tagging program monitors numbers of nesting hawksbill turtles on beaches 1-7 on Rosemary Island in the Dampier Archipelago. Beach 6 is the index beach. New and remigrant nesting turtles are tagged and data (carapace measurements, egg counts etc) are collected. Data are sent to DEC's Science Division in Woodvale. DEC Pilbara Region produces basic summary reports to meet DEC Animal Ethics Committee requirements. These are held at the DEC office in Karratha.

To monitor the number and location of seabird sightings within the Ningaloo Marine Park.

The movements, diving behaviour and thermal environment occupied by female olive ridley turtles Lepidochelys olivacea in northern Australia were determined through satellite telemetry, during the post-nesting migration. Satellite-relayed data loggers (SRDLs) were attached to the carapaces of 4 female olive ridley turtles nesting in the Wessel Islands of Arnhem Land in the Northern Territory of Australia (Graham Island: 11° 45’ S, 135° 57’ E and Wunpirri Island: 11° 36’ S, 136° 05’ E). This metadata record, represents several different datasets listed hereafter, which can all be accessed through a multi-WFS service. CTD - parameters measured by the instruments include time, temperature, and depth. The data represented by this record are presented in delayed mode. Diving - parameters measured by the instruments include start and end time and longitude/latitude of each individual dive, post-dive surface duration, dive duration, maximum dive depth, intermediate dive depths and times. The diving data represented by this record are presented in delayed mode. Haulout - a haulout begins when the SRDL has been continuously dry for a specified length of time (usually 10 minutes). It ends when continuously wet for another interval (usually 40 seconds). Haulout data parameters measured by the instruments include haulout start and end dates and longitude/latitude, and haulout number. The haulout data represented by this record are presented in delayed mode. Argos locations - parameters measured by the instruments include time, longitude, latitude, location quality, along with other diagnostic information provided by Argos (http://www.argos-system.org/). The Argos data represented by this record are presented in delayed mode. Summary Statistics - as well as sending records of individual events such as dives and haulouts, the SRDL also calculates summary statistics of those events over a specified time period (usually 3, 4 or 6 hours). Summary statistics computed by the instruments include the proportion of time spent diving, at the surface and hauled-out, the number of dives, and the average, standard deviation and maximum dive duration and dive depth during each summary period. These statistics are based on all the data recorded by the SRDL and so are not prone to distortion by variations in the efficiency of transmission via Argos. The summary data represented by this record are presented in delayed mode. Note that it is impossible to subset this particular dataset using a bounding box as there is no latitude, longitude coordinates associated with each entry.

Monitoring, identification & counting tracks made by nesting turtles, nesting success and impact of humans, around Cemetery Beach, Pretty Pool Beach & Eighty Mile Beach (Caravan Park & Anna Plains Station).

This dataset consists of the home ranges and satellite tracks taken from eleven dugongs and ten green turtles. Methods: Fast-acquisition satellite telemetry was used to track eleven dugongs and ten green turtles at two geographically distinct foraging locations in Queensland, Australia to evaluate the inter- and intra-species spatial relationships and assess the efficacy of existing protection zones. Home-range analysis and bathymetric modeling were used to determine spatial use and compared with existing protection areas using GIS. Raw, unfiltered tracking data were collected using fast acquisition GPS satellite transmitters attached to six dugongs (three females and three males) and four adult female green sea turtles near Mabuiag Island, Torres Strait, Australia in July 2009 and September 2010, and five dugongs (four females and one male) and six female green sea turtles (five adults and one prepubescent) in Shoalwater Bay, Australia in June/July 2012. The dugongs were captured using the dermal hold fast technique in Torres Strait and the standard rodeo technique in Shoalwater Bay. At both locations, the dugongs were fitted with Telonics Gen 4 GPS/ARGOS marine units attached to a 3 m tether linked to a padded tailstock harness. The green turtles were captured using the standard rodeo technique, brought to Mabuiag Island (Torres Strait) or MacDonald Point (Shoalwater Bay), and fitted with one of four types of satellite transmitters (Sirtrack F4G 291A, Wildlife Computers SPLASH10 BF-273A and Splash10 BF-273C, or SMRU SRDL 9000x). Each transmitter was attached to the carapace using the methods described in Shimada et al. (2012). Each turtle was released from shore the day after capture. Dugong units were programmed to collect a GPS position hourly; turtle units every 30 minutes. All units were programmed with a five minute repeat in case a signal was not received when the animal surfaced. Home-ranges were calculated for each animal using data from the entire period in which they were tracked and were calculated using fixed kernel density estimation with bandwidths selected by likelihood cross-validation (CVh). Kernel densities and bandwidths were calculated using the Geospatial Modelling Environment (GME), an extension to ArcGIS, with a resolution of 50 m. For a more detailed description of the methods see Gredzens(2014). Format: This dataset consists of shapefiles for the satellite tracks (lines and points) for the 21 animals as well as shapefiles for the calculated home ranges.

This long-standing marine turtle tagging program monitors numbers of nesting flatback turtles on Cowrie Beach on Mundabullangana Station. New and remigrant nesting turtles are tagged and data (carapace measurements, egg counts etc) are collected. Data are sent to DEC's Science Division in Woodvale. DEC Pilbara Region produces basic summary reports to meet DEC Animal Ethics Committee requirements. These are held at the DEC office in Karratha.

The WPCTP is a local community group that monitors turtle nesting activity and identifies threats/disturbances to nesting turtles and hatchlings on Bells Beach near Wickham. The program is part of a coordinated and concerted effort in the conservation and recovery of marine turtles and their habitats along the Pilbara coast. The WPCTP is supported by the Department of Environment and Conservation (DEC) and the Ningaloo Turtle Program (including Cape Conservation Group and WWF Australia) and is funded by Rio Tinto Iron Ore (RTIO)

Effective management of marine turtle data is essential to maximize their research value and enable timely population assessments and recovery monitoring. To provide such capabilities at the National Marine Fisheries Service, a comprehensive Turtle Data Processing System (TDPS, formally called Marine Turtle Data Management System) was created. The system was written in DBase III and Clipper and implemented on IBM/PC-compatible computers running under MS-DOS. As of 2017, TDPS was updated into Microsoft Access. The TDPS is modular, supporting data of various types. Cross-referencing and multiple-encounter analysis are enabled through a core database file of individual turtle identifications, based on uniquely-inscribed flipper tags and passive-integrated transponder tags.

The objectives of this project are to use novel satellite tracking methods to provide improved estimation of threats at foraging areas and along migration routes for oceanic stage sea turtles in the Northeast Distant Region of the Atlantic Ocean (NED) and to characterize the in-water habitats used by small, oceanic stage loggerheads (Caretta caretta) so that we better understand the features that likely define their nursery habitats and the potential risks and hazards to the smallest life stages of sea turtle. To accomplish these objectives, our strategy included collaborating with cooperative fishermen in the NED to capture and satellite tag small (30 cm length) loggerhead sea turtles. Using novel satellite telemetry techniques, we were to identify the fine-scale habitat selection, movements, and dispersal of small oceanic loggerheads in the NED.
