Abstract:

The remotely operated undulating towed vehicle known as the scanfish was equipped with a Sea-Bird Scientific fastcast CTD (SBE-49) and oxygen sensor (SBE-43), Sea-Bird Scientific-Satlantic OCR-507 multispectral radiometer, and four Sea-Bird Scientific-WET Labs optical instruments: Spectral Absorption and Attenuation meter (AC-s), ECO Triplet Fluorimeter (FL3: chlorophyll-a, Color Dissolved Organic Matter (CDOM) and Phycoerythrin), ECO Triplet Backscattering sensor (BB3: 470 nm, 532 nm, 660 nm) and a C-Star Transmissometer. The scanfish was towed continuously from the R/V Pelican cruise PE16-19A for four days (2016-03-31 22:45 UTC through 2016-04-02 23:47 UTC) during the first leg of the Spring CONCORDE cruise that took place from 2016-03-29 to 2016-04-03. The dataset includes only the raw files. Processed data can be found under GRIIDC Unique Dataset Identifier (UDI) R4.x260.000:0086 (DOI: 10.7266/N71N7ZK4).
