What are the net transfers and reactions that define the C cycle in the coastal margins?. Air-sea exchange (best known; maybe smallest. Margin-open ocean exchange not well understood. Large river inputs fairly well known; estuarine exchange overlooked ??.

Measurement laundry list: Do what we already do well in places/times we aren’t doing it enough (More platform and ship of opportunity observations of air and water pCO2, bio-optical parameters) Pursue emergent sensing technologies to expand parameter measurement suite (e.g. nutrients, TCO2; pH; DOC; trace gases; trace elements; consideration of OA requirements). Develop new technologies to expand our process-level understanding of key rates and transports (C transport; biological rates; tracer and proxy development). Promote C-relevant measurement in OOI, IOOS etc. Don’t lose current capabilities in in-water and satellite remote-sensing!
Synthesis and modeling synergies: Development of remote-sensing algorithms to quantify C-cycle transfers and rates. Figure out ways to move beyond concentration/stock measurement to transfers/transformations Seek out under-utilized datasets (requires reaching out to non-traditional entities-- local and state municipalities; EPA; USGS, fisheries-- and assimilation of C-relevant, not just C-specific, data. Work with modeling community to provide key modeling constraints; model-motivated measurement programs. Cross land-ocean (academic) boundaries to incorporate water-shed study with estuarine/coastal-ocean study.
Synthesis and modeling synergies, cont’d: 6) Develop collaborations-of-opportunity, e.g. for sampling by researchers who might work in areas of interest, but without technical resources for desired measurements. 7) Incorporate non-aqueous transfers into ocean margin settings (e.g. atmospheric deposition; direct uptake of atmospheric CO2 by emergent aquatic vegetation). Figure out strategy for dealing with non-point ‘terrestrial’ inputs (marshes, wetlands, sub-marine groundwater discharge. Determine the optimal approach to establishing comparative data-bases; model intercomparisons.
