In 2022, the hydrochemistry of surface water was monitored at Helgoland Roads station on every workday, typically before 9 a.m. Temperature was measured on board immediately after sampling. Visibility was measured immediately on board using a Secchi Disk. Salinity, dissolved inorganic nutrients, pH and oxygen were measured from a bucket sample in the laboratory. Further information regarding the methodology and the devices used can be found in the metadata description.
The dataset is a set of photos of marine litter at the seafloor and corresponding coordinates. The photos were taken in the southernmost North and Baltic seas, between 30.11.2022 and 12.12.2022 during the Walther Herwig III 462 research cruise (Date begin: 29.11.2022 - Date end: 14.12.2022, harbor begin: Bremerhaven - harbor end: Bremerhaven) . The video system used consists of a GoPro HERO 9 black in an aluminium case mounted in the front of the sledge and two lights with a total of 7200 lumen. Three laser pointers mounted in an equilateral triangle (laser center point distance 25.5 cm) provided the size reference for the video observation. The photos were taken as part of a study to visually quantify the amount of marine letter in the seafloor and compare this value with bottom trawl data.
