Lobate ctenophore in situ swimming velocities and morphometrics sampled off of Woods Hole, Massachusetts and the Kona coast of Hawaii, USA from 2019 to 2022 (NCEI Accession 0291623)

This dataset contains biological, physical, and survey - biological data collected from 2019-08-15 to 2022-04-20. These data include genus and water temperature. The instruments used to collect these data include Self-Contained Underwater Breathing Apparatus and Underwater Camera. These data were collected by John H. Costello of Providence College, Sean Colin of Roger Williams University, Kelly Rakow Sutherland of University of Oregon, and Brad J. Gemmell of University of South Florida as part of the "Collaborative Research: Quantifying the trophic roles of epipelagic ctenophores (Ocean Ctenos)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2024-01-03.

Lobate ctenophore in situ swimming velocities and morphometrics

Dataset Description:
Methods and Sampling:
Data were collected using SCUBA diving techniques off Woods Hole, Massachusetts, USA (41° 31' 36.7" N 70° 40' 30.6"W) and off the Kona coast of Hawaii, USA (19° 40' 10.5" N 156° 02' 46.4" W). Morphometric and behavioral data were collected using recordings from custom video underwater video/imaging systems of animals in their natural environment using SCUBA techniques. Morphometric parameters were quantified by recording undisturbed individuals in the water column using high-resolution 4K video cameras (Sony AX100) with brightfield collimated-light optical systems (Townsend et al. 2020). From the video, we measured the total length, the lobe length, the lobe width, and opening width. In situ swimming speed was quantified from the videos by measuring the speed relative to ambient particles near the ctenophore. Only particles that were in the plane with the ctenophore and passed between or adjacent to the lobes were selected.
