Feb 14, 2025 - Plastic pollution
Yesson, Chris; Clark, Malcolm R; Taylor, M; Rogers, A D, 2025, "Lists of seamounts and knolls in different formats", https://doi.org/10.1594/PANGAEA.757564
Seamounts and knolls are 'undersea mountains', the former rising more than 1000 m from the sea floor. These features provide important habitats for aquatic predators, demersal deep-sea fish and benthic invertebrates. However most seamounts have not been surveyed and their numbers and locations are not well known. Previous efforts to locate and quan... |
Feb 3, 2025 - Coral Reef Resilience and Recovery in the Chagos Archipelago
Khrizman, Alexandra; Lindhart, Mathilde; Mucciarone, David; Takeshita, Yuichiro; Monismith, Stephen; Boles, Elisabeth; Dunbar, Robert, 2025, "Data - Reef community productivity and calcification – spatial and temporal variability in recovering coral reefs", https://doi.org/10.25740/MM452CT6249, Stanford Digital Repository
Coral reef Net Community Production (NCP) and Net Community Calcification (NCC) are measures of the functioning of reef ecosystems, currently under threat due to multiple anthropogenic stressors. We assessed these rates using a benthic gradient-flux approach (BEAMS system) on forereef and lagoon coral reefs that were recovering from the major 2015-...The metadata for the Dataset was harvested from DataCite.
