Diver surveys of rock patches documented 38 species of fish and invertebrates and found 38% of the larger diameter rocks (10-100 cm) flipped with the encrusted live coral and algae side left face down. We developed a set of "electric rocks" (artificial rocks fitted with event loggers) to record the date and time of any movement. We deployed the rocks in multiple clusters on the terraced slope of the seal colony atoll (French Frigate Shoals) close to the beach haulout and at two sites further away on the summits of neighboring banks. The goal was to expand temporal monitoring (diurnally and seasonally) of the seal's use of mesophotic rubble patches without requiring further instrumentation of monk seals. The data from the electric rocks showed patterns consistent with the behavior seen from the seal-mounted video, including rapid rock-to-rock searching and more movements closer to seal haulouts. The electric rocks detected more rock tips on the atoll terrace than on the banks, with higher counts seen during the day at the bank summits. Seasonally, both the terrace and bank detected more movements in summer and fall months consistent with the monk seal's reproductive pupping and molting season than during the rest of the year, suggesting some seasonal change in the foraging habitat of monk seals. Abstract above is from the Journal Endangered Species Research publication on the topic. This metadata includes sub files that hold the different types of data used in the publication (observations from Seal-mounted video data, diver surveys of the mesophotic habitat and fish community and the raw data from the event loggers in the form of electric rocks. completed Barbieri, Michelle M 808-725-5734 1845 Wasp Blvd. Honolulu HI 96818 USA michelle.barbieri@noaa.gov pointOfContact Mercer, Tracy (808)725-5718 1845 Wasp Blvd. Honolulu HI 96818 USA tracy.mercer@noaa.gov email with questions custodian notPlanned Data collected for the three years study as a pilot project and then discontinued EARTH SCIENCE theme Global Change Master Directory (GCMD) Science Keywords 17.0 EOP ESD PIFSC theme DOC/NOAA/NMFS/PIFSC > Pacific Islands Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

The depth range is between 30-80 meters The area of study is the mesophotic terrace outside the north barrier reef of French Frigate Shoals (FFS, 50-80 m) and the mesophotic summits (40-80 m) of Southeast Brooks Bank and Middle Brooks Bank. The area falls between the Middle Brooks site to the west (N 24° 10.060 W166° 59.136) and the Trig area at FFS atoll (N 23° 53.364 W 166° 14.376) Between this span of dates all the habitat surveys were conducted and the electric rock data loggers were deployed and recovered.
