    • AFSC/NMML/CCEP: Raw telemetry data for California sea lions and northern fur seals in waters off California, Oregon, and Washington

    Metadata Updated: April 1, 2024

    The purpose of this project was to obtain data that are pertinent to assessing aspects of the distribution and foraging ecology of pinnipeds inhabiting the California Current. The California Current Ecosystem Program has attached satellite instruments and/or archival time-depth recorders on pinnipeds inhabiting waters off Washington, Oregon, and California to examine their haulout and at-sea spatial distribution, diving behaviors, and movement patterns at varying temporal scales. We aim to integrate telemetry data with aspects of their physiology and diet to assess sex/age-related differences by conspecifics or intra-specific differences among seals, sea lions, or fur seals in the California Current. Locations are calculated and provided by the Argos satellite system (http://www.argos-system.org/). Additional software are required to decode these data. Data are, generally, in the same format as originally delivered from Argos/CLS America and no quality assurance or quality control measures have been implemented.

    Lineage Instrumentation – Animals were outfitted with a platform transmitter terminal Kiwisat PTTs (SirTrack, Havelock North, New Zealand) and a VHF radio transmitter (Model MM130, Advanced Telemetry Systems, Isanti, Minnesota). During 2005, individuals were instrumented with KiwiSat tags, VHF transmitters, and time-depth recorders (TDRs; Mk9, Wildlife Computers, Redmond, Washington). During 2006, SPLASH tags (Wildlife Computers), which have location and time-depth recording capabilities, were attached to individuals. During 2007, sea lions were equipped with a PTT only (SPOT5; Wildlife Computers). Instruments were attached directly onto the animal’s pelage or onto a neoprene patch that was affixed to the pelage located dorsally between the scapulae. The adhesive (5-minute epoxy, DevconTM, Danvers, Massachusetts) was applied after the animal’s pelage was cleaned, degreased with acetone, and dried using a towel or compressed air. Once morphometric data and biological samples were collected, the epoxy had hardened, and sedation (when applied) wore off, the animal was released. Efforts were made to recapture individuals equipped with TDRs or SPLASH tags so that archival dive information could be obtained. Location data (i.e. latitude, longitude) were obtained. Data were transmitted to the Argos Data Location and Collection System (Service Argos 1996). To extend battery life, the Kiwisat PTTs were programmed with either a 12 hr (4 on/8 off) or 72 hr (24 on/48 off) duty cycle. To maximize the number of transmissions received by Argos satellites, tag transmission periods were synchronized with periods of optimal satellite coverage using NASA’s J-Pass software (ver. 2.0). These data are represented as a zipped archive of all messages and data files delivered from Argos/CLS America to the California Current Ecosystems Program. Data may have been delivered via direct electronic download, email or CD. The message formats have changed over the years and are preserved as close to the 'as delivered' state as possible.
