Abstract:
This dataset contains data from three mahi-mahi (Coryphaena hippurus) satellite tags deployed in the Florida Straights from the R/V Yellowfin cruise YF20181217 (2018-12-17). Data included are temperature, depths, and acceleration values generated by pop-up satellite archival tags (PSATs, Wildlife Computers, Inc.) attached to released mahi-mahi. The full Argos returned data are included as well as a summary of the tagging and release dates and times. Two Readme documents thoroughly document the Argos files and variables. This dataset supports the publication: Schlenker, L.S., Faillettaz, R., Stieglitz, J.D., Lam, C.H., Hoenig, R.H., Cox, G.K., Heuer, R.M., Pasparakis, C., Benetti, D.D., Paris, C.B., Grosell, M. “Remote predictions of mahi-mahi (Coryphaena hippurus) spawning in the open ocean using summarized accelerometry data.” Frontiers in Marine Science.

Satellite tag data from three mahi-mahi (Coryphaena hippurus) collected in the North Atlantic from 2018-12-24 to 2019-02-13, deployed in the Florida Straits on 2018-12-17 aboard R/V Yellowfin cruise YF20181217.

Purpose:
Understanding the migrations, habitat use, and acceleration behavior of wild mahi-mahi (Coryphaena hippurus) not exposed to oil.
Data Parameters and Units:
The summarized tag data include Argos ID, PSAT number, location captured and released, vessel captured (Yellowfin), date tagged, sex, FL (fork-length of tagged mahi-mahi [cm]), time hooked (EST, [hh:mm:ss]), total angling time [mm:ss], total handling time [mm:ss]), hours spent in the recovery tank, catch latitude [decimal degrees], catch longitude [decimal degrees], release latitude [decimal degrees], release longitude [decimal degrees], fish release date, fish release time (EST), fish release time (GMT), tag days deployed (number of days PSAT was attached to living mahi-mahi), date tag off fish, time tag off fish (GMT), tag pop-up date (the date that PSAT began transmitting data), date first transmission, time first transmission, release notes.
Other reported variables include depth [m] and temperature [degrees C]. The complete transmitted Argos datastream is also included in this dataset.
Methods:
Mahi-mahi were captured using hook and line angling, were measured for fork-length, tagged with a pop-up satellite archival tag. Fish were held for ~1 hour in an oxygenated flow through 500 L tank for recovery before release. This dataset includes temperature (Celsius), depth (meters), light (Wcm-2 at 440nm), and summarized acceleration (g) collected from satellite tags attached to wild adult mahi-mahi.
