A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

Bivalve Gut Microbiome Responses to Sediment Characteristics and Anthropogenic Activities in Cerastoderma edule (Linnaeus, 1758)

Abstract Estuaries are dynamic ecosystems influenced by fluctuating environmental conditions and sediment-associated contamination, which may affect host-associated microbiomes. This study investigated the gut microbiome of the bivalve Cerastoderma edule across three estuarine si...

Quaternary Arctic planktonic foraminifera: morphological differentiation and taxonomic reassessment of subpolar spinose taxa

Abstract. Planktonic foraminifera in the modern Arctic Ocean are dominated by the non-spinose polar species Neogloboquadrina pachyderma. Acmes of two spinose, presumed subpolar taxa in Quaternary central Arctic sediment cores are therefore anomalous, implying significantly differ...
