| Resumo | Global carbon balances lack a comprehensive inventory of the flux of CO2 between coastal waters and the atmosphere that accounts for the diverse range of spatial and mechanistic heterogeneity of earth systems, not to mention the entire surface area of the earth. Here, we evaluate two satellite remote sensing based approaches to resolve coastal CO2 fluxes in two types/sizes of coastal systems. Apalachicola Bay, Florida (AB) was used to evaluate fine scale dynamics in a semi-enclosed bay with blackwater river inputs. The Amazon River plume (ARP) was used to evaluate much larger spatial scales in a river-dominated shelf setting. In AB, we used chlorophyll and temperature products from VIIRS imagery, validated with in situ measurements, along with a previously established CDOM algorithm for the bay to map salinity. These 3 parameters were used to obtain multi-variable linear regression relationships for estimating pH, and pCO2 was estimated based on the in situ pH:pCO2 relationship. CO2 fluxes were highest in winter and summer corresponding to high river flow and warm water temperature and lower fluxes in spring and fall likely due to CO2 fixation via photosynthesis and low water temperatures with reduced river flow, respectively. The annual average flux for Apalachicola Bay from 2015-2016 was 3.52 mol m-2 y-1, or 0.034 Tg C y-1 for the entire bay. In the ARP we modeled pCO2 from 2010-2014 based on sea surface salinity and temperature retrieved from SMOS and OISST, respectively. The ARP was a net sink of CO2 during falling and low water periods, but a net source during rising and high water, resulting in an annual average flux of 1.10 mol m-2 y-1 to the atmosphere, or 5.6 ± 7.2 Tg C y-1 across the extent of the ARP. These findings contradict the current paradigm that the ARP is a net sink of CO2, and are driven by observations of CO2-rich waters near the coast during rising and high water. Both approaches identified unique seasonal patterns driving net positive estuarine fluxes of CO2 to the atmosphere. The approach used in the Amazon still has spatial gaps considering it only covered waters between 20-35 psu salinity and further than 100 km offshore. The observations of dynamic intra- and inter-annual patterns illustrate the importance of developing more accurate and high-resolution approaches for examining carbon cycling parameters remotely. | |||
