Field Activity 2025-003-FA

Identifier 2025-003-FA
Alternate names 2025 CNEWTS
Purpose To collect data on lateral fluxes from salt marshes.
Location Salt marshes on Cape Cod, including Chatham and Mashpee.
Summary Surface water and porewater sample collections are completed. Samples are stored in WHSC walk-in freezers and refrigerators or distributed to external laboratories for analysis. Gas flux and CTD measurements are completed. Raw data files and field notes are stored in WHSC network folders.
Info derived Surface water and porewater geochemistry, meteorological data, water flux data, elevation data, GHG fluxes.
