Conductivity Temperature and Depth (CTD) Data from the EL25-Bornholm Cruise with R/V Electra, 29 - 30 May 2025

This package contains CTD data collected during the fourth cruise of a research project entitled "Evaluating the recovery trajectory of benthic community structure and function after cessation of bottom trawling."

The data were collected in the Bornholm Strait in the Baltic Sea, between 29th and 30th of May 2025.

Research Vessel: R/V Electra af Askö

The cruise was conducted with support from FORMAS and SWERVE.

Data Description

This package contains both the raw CTD sensor data (.hex files) and the pre-processed files (.cnv). Note that these data are not quality checked. The pre-processing involves conversion of the raw data into scientific units, filtering, averaging, binning, and calculating additional oceanographic parameters. All the pre-processing is performed by Seabird's Seasave software modules. Processing parameters are found in the .cnv file headers.

The vertical resolution of the data is 0.25 meters.
