Processed Acoustic Backscatter, Sidescan and Swath Bathymetry Data from the Cascadia Margin acquired during R/V Marcus G. Langseth expedition MGL2104 (2021)
This data set was acquired with a Kongsberg Maritime EM122 Multibeam Sonar during R/V Marcus G. Langseth expedition MGL2104 conducted in 2021 (Chief Scientist: Dr. Suzanne Carbotte, Investigators: Dr. Jeffrey Beeson, Dr. Suzanne Carbotte). These data files are of MBSystem-compatible format (format 121, Generic Sonar Format) and include Acoustic Backscatter, Sidescan and Swath Bathymetry data that were processed after acquisition. This data was processed by OSU and is included in the Global Multi-Resolution Topography (GMRT) Synthesis (version 4.0). Data were acquired as part of the project(s): Collaborative Research: Illuminating the Cascadia plate boundary zone and accretionary wedge with a regional-scale ultra-long offset multi-channel seismic study. Funding was provided by NSF award: OCE18-27452.

This data set was acquired with the LDEO Multi-Channel Seismic system during a seismic survey of the Queen Charlotte Fault Zone, as part of R/V Marcus G. Langseth cruise MGL2105 (Chief Scientist Lindsay Worthington). The data files are in U.K.O.O.A. P1/90 format and contain Seismic Navigation data that has not been processed. The data set was acquired as part of the project called Relationship between plate boundary obliquity, strain accommodation, and fault zone geometry at oceanic-continental transforms: The Queen Charlotte Fault. Funding was provided by NSF awards OCE18-24927 and OCE21-28783.more » « less

Bathymetric data were collected during a total of 19 AUV Sentry dives conducted from R/V Atlantis and R/V Roger Revelle during 2018 Atlantis cruise AT42-06 (two dives); 2019 Atlantis cruise AT42-21 (ten dives); and, 2021 Revelle cruise RR2102 (seven dives). Track lines were spaced 170 m apart, with Sentry about 65 m above bottom, collecting multibeam data using a 400 kHz Reson 7125 system in 2018, and a 400 kHz Kongsberg EM2040 system in 2019 and 2021. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. Sonar data from all 19 dives were processed together using the open-source MB-System software, and were gridded at 1 m × 1 m node resolution using a beam footprint calculated with the angular beam widths and weighted by local slope. The grid file is in GMT-compatible netCDF format, in un-projected geographic coordinates. Funding was provided by National Science Foundation awards OCE-1834797, OCE1949485, OCE-1948936, and OCE-1949938.more » « less

This dataset contains measurements of the diameter and area of Antarctic krill (Euphausia superba) oocytes collected from the northern Antarctic Peninsula during the austral winter from 2012 to 2016 (August each year). Female oocytes were examined using the "squash technique" developed by Cuzin-Roudy and Amsler (1991) for assessing ovarian development and sexual maturity. The squash method provides a detailed view of oocyte size, which serves as an indicator of reproductive status and energy allocation during the winter months. Data were collected and processed according to the methods described by Steinke et al. (2024). The dataset includes .csv files containing oocyte diameter and area measurements for individual female krill. These data are valuable for understanding krill reproductive cycles and their ecological responses to environmental variability. Data users should acknowledge the project and grant number, as well as credit Dr. Kim Bernard, Dr. Kirsten Steinke, and Dr. Christian Reiss. The research was conducted in collaboration with the US National Oceanic and Atmospheric Administration Antarctic Marine Living Resources group.more » « less
