Remotelysensed OC data provides an integrated quasi-steady state observation of the whole of the global ocean and all \r\ntypes of ocean environments (seasonally-variable nutrient & light climates): oligotrophic gyres; equatorial ecosystems; mid and high-latitude, seasonally-productive systems; highly-productive upwelling and convergent zones. Primary production (PP) derived from OC data gives an estimate of the total C sequestered by phytoplankton (~35-70 Gt C yr-1\r\n).  Hitherto EO-based PP models have used chlorophyll (Chla) as the state variable. New methods invoke Inherent Optical Properties (IOPs; the spectral absorption & \r\nbackscattering of the ocean).  Using IOP models and IOP-OC data, we will describe the pelagic ocean C-cycle, with improved PP models, re-cycling rates and respiration, to: \r\n(i) determine phytoplankton function types (PFTs) used in ecosystem models; (ii) provide parameter data for ecosystem models; (iii) partition the pelagic C-pool into particulate, dissolved, organic and inorganic components.","keywords":"NCEO, carbon, biogeochemistry","status":"completed","publicationState":"published","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/5495/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/5496/?format=json"],"observationCollection":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/8584/?format=json"],"parentProject":"https://catalogue.ceda.ac.uk/api/v2/projects/5001/?format=json","subProject":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/51848/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/51846/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/51847/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/51845/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/33926/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/33925/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/54787/?format=json"]}
