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

Abstract:

This dataset includes morphological and swimming data of lobate ctenophores swimming in the field. The data were collected by SCUBA divers using videography off of Woods Hole, Massachusetts (41°30'48.14"N, 70°41'36.56"W) and the Kona coast of Hawaii (19°34'55.24"N, 156°12'56.60"W) from 2019 to 2022. The videos were collected at various dates and locations depending on the lobate species.

Methods & 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.

Data Processing Description

Videos were processed using ImageJ software.

BCO-DMO Processing

- Adjusted field/parameter names to comply with BCO-DMO naming conventions.
- Converted dates to format: YYYY-MM-DD.
- Latitude and longitude values were converted to decimal degrees, where negative values denote the Southern and Western hemispheres.
- Rounded values for latitude and longitude to 3 decimal places.

Generic Name: Self-Contained Underwater Breathing Apparatus

Acronym: SCUBA

Generic Description:

The self-contained underwater breathing apparatus or scuba diving system is the result of technological developments and innovations that began almost 300 years ago. Scuba diving is the most extensively used system for breathing underwater by recreational divers throughout the world and in various forms is also widely used to perform underwater work for military, scientific, and commercial purposes.
