The purpose of measuring jelly plankton in the marine environment is primarily to detect changes in the marine food web. The national monitoring program is financed by the Swedish Agency for Marine and Water Management. Monitoring is performed by Gothenburg University. Data are stored in the Swedish Ocean Archive (SHARK) by the Swedish Meteorological and Hydrological Institute (SMHI). Information about the program and the methods are available in Swedish at the website of Swedish Agency for Marine and Water Management, https://www.havochvatten.se/vagledning-foreskrifter-och-lagar/vagledningar/ovriga-vagledningar/overvakningsmanualer-for-miljoovervakning/overvakningsmanualer/geleplankton.html

Dataset gives a baseline for micro- and mesoplastic pollution distribution in 24 beaches along the Latvian coastline (Northern Europe, Baltic states), filling the existing knowledge gap and contributing to the global understanding of microplastic particles presence, transport, and the processes governing its dynamics. We also highlight citizen science as a fundamental tool to support data collection and raise awareness about microplastic pollution, as samples were collected by up to 250 volunteers during organized campaigns (Dimante-Deimantovica et al. 2023).

Beach litter monitoring data from the Swedish coastline of Kattegat, the Sound and the Baltic Sea

Displays wrecks from the National Monuments Service’s Wreck Inventory of Ireland Database (WIID) for which there is a recorded location. There is data held within the WIID on a large number of wrecks for which we have no precise recorded location, co-ordinate or known extent. Of the approximate 18,000 records, only 4,000 have precise locations leaving approximately 14,000 wrecks in the WIID database for which a location has yet to be confirmed. The location given equates with the known approximate centre point of the wreck and is not indicative of its geographic or spatial extent. Wrecks in the database have a summary description, providing information on the original vessel, their history, voyage, cargo, passengers and the story of its loss, where known. The data has been collated from a variety of sources including INFOMAR, UKHO, wrecksite.eu and uboat.net.
