This paper aims to investigate the links between in-water optical properties in four Swedish bays (from the northern Baltic proper up to the Bothnian bay) and the land use and land cover (LULC) in the respective catchment of each bay. The optical properties were measured in situ over the last decade by various research and monitoring groups while the LULC in each bay was classified using the Copernicus Land Monitoring Service based on Landsat 8\/OLI data. The absorption coefficient of colored dissolve organic matter (CDOM) at 440 nm, aCDOM (440), was significantly correlated to Wetlands which may act as sources of CDOM, while Developed areas (Agricultural and Urban classes) were negatively correlated. The Agriculture class was also negatively related to suspended particulate organic matter (SPOM), whilst Coniferous Forests and Mixed Forests as well as Meadows were positively correlated. SPOM seems thus to mostly originate from Natural classes, possibly due to the release of pollen and other organic matter. Overall, the methods applied here allow for a better understanding of effects of land use and land cover on the bio-optical properties, and thus coastal water quality, on a macroscopic scale.<\/jats:p>","DOI":"10.3390\/rs16010176","type":"journal-article","created":{"date-parts":[[2023,12,31]],"date-time":"2023-12-31T06:37:12Z","timestamp":1704004632000},"page":"176","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Links between Land Cover and In-Water Optical Properties in Four Optically Contrasting Swedish Bays"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0992-7203","authenticated-orcid":false,"given":"Susanne","family":"Kratzer","sequence":"first","affiliation":[{"name":"Department of Ecology, Environment and Plant Sciences (DEEP), Stockholm University, 10691 Stockholm, Sweden"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-7589-8609","authenticated-orcid":false,"given":"Martin","family":"Allart","sequence":"additional","affiliation":[{"name":"Department of Ecology, Environment and Plant Sciences (DEEP), Stockholm University, 10691 Stockholm, Sweden"},{"name":"National Institute of Applied Sciences (INSA), 20 Av.
