Fehr 20250919 spreadsheet Davie, Florida U.S. Geological Survey - Wetlands Aquatic Research Center https://doi.org/10.5066/P1GMEAV5 This release contains data from acceleration data logger (ADL) float packages designed to 'pop-off' in a set amount of time for recovery and platform terminal transmitter (PTT) satellite tags attached to 12 Kemp's ridley (Lepidochelys kempii) and 7 Loggerhead (Caretta caretta) turtles in several geographic locations, using the methods of Hart et al., 2013. These instrument packages collected acceleration, depth, environmental temperature, and spatial data. Pilot testing of the pop-off instrument packages was conducted in the Dry Tortugas (one Loggerhead) and Pascagoula, MS (one Kemp's ridley), in September 2018 and September 2019, respectively; data from these pilot tests are included in this data release. Ten packages (all Kemp's ridley) were applied to individuals caught during trawling operations in Ship Shoal, LA in July 2022. One Ship Shoal tag was not recovered. An additional 7 were applied to individuals caught in Sabine Banks, TX in July 2023 (6 Loggerhead, 1 Kemp's ridley): all tags recovered. Instrument data have been subset to the period that the ADL packages were directly attached to the individual, and satellite location data are provided in their entirety. These data were collected to investigate sea turtle behavior following capture and release during trawling operations using fine-scale acceleration data logger packages. All turtles tagged in 2022 and 2023 were outfitted with the axy-5 by Technosmart Inc. These tags were programmed to record acceleration at 50 Hz, the magnetic field at 2 Hz, and depth/temperature at 1 Hz. Individuals tagged in 2023 had a programming error that caused depth readings to be NULL and temperature readings to have coarse (1 C) resolution. The two pilot individuals in Pascagoula and the Dry Tortugas were outfitted with the G6A+ tag made by Cefas (Centre for environment, fisheries, and science) based in the United Kingdom. These tags were not outfitted with a magnetometer and therefore do not have a "*_Mag.csv" file. Temperature readings have been linearly interpolated to 1 Hz, and acceleration measurements were recorded at 25 Hz.

Data span the expected periods without known issues. Dataset is considered complete for the information presented, as described in the abstract. Users are advised to carefully read the rest of the metadata record for additional details. Individuals were caught and had custom ADL float packages and PTT satellite tags attached to them using the methodology of Hart et al., 2013. 2025 The ADL packages were designed to 'pop-off' for physical recovery of the instruments and data. These periods ranged from 10 hours to 4 days. 2025 ADL tags were recovered, and data were offloaded from the onboard storage devices. Data were recovered from the Technosmart tags using the software X Manager version 1.26.7, and DST Host version 7.0 was used for the Cefas tags. Data were then subset to the periods that the tags were directly attached to the individual using R version 4.4.2. 2025 Satellite data were downloaded from Wildlife Computers and are provided in their entirety with the exception of extreme outliers which were manually removed. 2025 BOEM_AccelerationFiles.zip Collection of comma separated values (CSV) files that contain acceleration data.
