{"cited_by_count":3924074,"description":"This cluster of papers focuses on the complex interactions between marine biogeochemistry, ecosystem dynamics, and environmental factors such as eutrophication, harmful algal blooms, and climate change. It explores the role of dissolved organic matter, nutrient limitation, and phytoplankton in the oceanic carbon cycle and highlights the impact of global warming on biological productivity and oxygen levels in the oceans.","display_name":"Marine and coastal ecosystems","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T10032","wikipedia":"https://en.wikipedia.org/wiki/Marine_biogeochemistry"},"field_id":"19","id":"T10032","keywords":[{"display_name":"phytoplankton","id":"phytoplankton","score":0.3833,"url":"https://openalex.org/keywords/phytoplankton"},{"display_name":"ocean carbon cycle","id":"ocean-carbon-cycle","score":0.7783,"url":"https://openalex.org/keywords/ocean-carbon-cycle"},{"display_name":"chlorophyll a","id":"chlorophyll-a","score":0.2934,"url":"https://openalex.org/keywords/chlorophyll-a"},{"display_name":"underway measurements","id":"underway-measurements","score":0.4952,"url":"https://openalex.org/keywords/underway-measurements"},{"display_name":"surface ocean CO2","id":"surface-ocean-co2","score":0.9259,"url":"https://openalex.org/keywords/surface-ocean-co2"},{"display_name":"nutrients","id":"nutrients","score":0.3031,"url":"https://openalex.org/keywords/nutrients"},{"display_name":"Southern Ocean","id":"southern-ocean","score":0.2217,"url":"https://openalex.org/keywords/southern-ocean"},{"display_name":"coastal waters","id":"coastal-waters","score":0.2497,"url":"https://openalex.org/keywords/coastal-waters"},{"display_name":"primary production","id":"primary-production","score":0.4011,"url":"https://openalex.org/keywords/primary-production"},{"display_name":"seawater chemistry","id":"seawater-chemistry","score":0.4644,"url":"https://openalex.org/keywords/seawater-chemistry"},{"display_name":"dissolved organic matter","id":"dissolved-organic-matter","score":0.291,"url":"https://openalex.org/keywords/dissolved-organic-matter"},{"display_name":"physical oceanography","id":"physical-oceanography","score":0.2819,"url":"https://openalex.org/keywords/physical-oceanography"},{"display_name":"partial pressure of CO2","id":"partial-pressure-of-co2","score":0.424,"url":"https://openalex.org/keywords/partial-pressure-of-co2"},{"display_name":"ocean color","id":"ocean-color","score":0.6611,"url":"https://openalex.org/keywords/ocean-color"},{"display_name":"phytoplankton biomass","id":"phytoplankton-biomass","score":0.5066,"url":"https://openalex.org/keywords/phytoplankton-biomass"},{"display_name":"dinoflagellates","id":"dinoflagellates","score":0.2407,"url":"https://openalex.org/keywords/dinoflagellates"},{"display_name":"ocean biogeochemistry","id":"ocean-biogeochemistry","score":0.5977,"url":"https://openalex.org/keywords/ocean-biogeochemistry"},{"display_name":"particulate organic carbon","id":"particulate-organic-carbon","score":0.4682,"url":"https://openalex.org/keywords/particulate-organic-carbon"},{"display_name":"phytoplankton community structure","id":"phytoplankton-community-composition","score":0.4593,"url":"https://openalex.org/keywords/phytoplankton-community-composition"},{"display_name":"water bottle samples","id":"water-bottle-samples","score":0.5177,"url":"https://openalex.org/keywords/water-bottle-samples"},{"display_name":"phytoplankton blooms","id":"phytoplankton-blooms","score":0.5387,"url":"https://openalex.org/keywords/phytoplankton-blooms"},{"display_name":"sea surface salinity","id":"sea-surface-salinity","score":0.3714,"url":"https://openalex.org/keywords/sea-surface-salinity"},{"display_name":"ocean primary productivity","id":"ocean-primary-productivity","score":0.6355,"url":"https://openalex.org/keywords/ocean-primary-productivity"},{"display_name":"dissolved inorganic carbon","id":"dissolved-inorganic-carbon","score":0.3611,"url":"https://openalex.org/keywords/dissolved-inorganic-carbon"},{"display_name":"fugacity of CO2","id":"fugacity-of-co2","score":0.8797,"url":"https://openalex.org/keywords/fugacity-of-co2"}],"legacy_keywords":["Dissolved Organic Matter","Eutrophication","Harmful Algal Blooms","Oceanic Carbon Cycle","Phytoplankton","Global Warming","Nutrient Limitation","Biological Productivity","Oceanic Oxygen Levels","Climate Change"],"openalex_id":"https://openalex.org/T10032","source_created_date":"2024-01-23T15:27:05","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1910","url":"/topics/T10032","works_api_url":"https://api.openalex.org/works?filter=topics.id:T10032","works_count":236658,"label":"Marine and coastal ecosystems","provider":"openalex","revision":"3c45208420ca3f0d","taxonomy_revision":"f050b5d4780b1289","title":"Marine and coastal ecosystems","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36042867412436083","address_version":"morton4x16-v1","coordinates":[3,19,1910,10032],"answer_status":"Directory metadata;
