DOM composition in Altamaha River and Sapelo Sound estuaries measured by FT-ICR mass spectrometry in 2017 (April, July, October) and 2018 (January and October)
Extreme events such as hurricanes and tropical storms often result in large fluxes of dissolved organic carbon (DOC) to estuaries. Precipitation associated with tropical storms may be increasing in the southeastern U.S., which can potentially impact dissolved organic matter (DOM) dynamics and cycling in coastal systems. Here, DOM composition at the Altamaha River and Estuary (Georgia, U.S.A.) was investigated over multiple years capturing seasonal variations in river discharge, high precipitation events, and the passage of two hurricanes which resulted in substantial storm surges. Optical measurements of DOM indicate that the terrigenous signature in the estuary is linearly related to freshwater content and is similar after extreme events with or without a storm surge and during peak river flow. Molecular level analysis revealed significant differences, however, with a large increase of highly aromatic compounds after extreme events exceeding what would be expected by freshwater content alone. Although extreme events are often followed by increased DOC biodegradation, the terrigenous material added during those events does not appear to be more labile than the remainder of the DOM pool that was captured by ultrahigh-resolution mass spectrometry analysis. This suggests that the added terrigenous organic matter may be exported to the coastal ocean, while a fraction of the organic matter that co-varied with the terrigenous DOM may contribute to the increased biomineralization in the estuary, with implications to carbon processing in coastal areas.

Underwater temperature, light, and dissolved oxygen data from 3 mini-buoys in Lake Sunapee, NH, USA from June to October 2018
Three mini-buoys were deployed during a portion of the ice-off period of 2018 in Lake Sunapee, NH, USA with HOBO temperature sensors at various depths below the water’s surface. Temperature data were collected using HOBO pendant temperature and HOBO pendant temperature/light sensors at descending depths between 0.1m and the nearest whole and/or half meter increments below the water surface and above the sediment/water interface at 10 minute intervals. Two buoys (Georges Mills and Herrick Cove) also had miniDOT (PME) dissolved oxygen and temperature sensors placed 1.75 meters below the surface. The buoys were located in cove areas of the lake in the north east arm of the lake (Herrick Cove, 0.1m – 6.5m), the west side of the southern area of the lake near Lake Sunapee State Beach (State Beach, 0.1m – 2.5m) and the northwest arm of the lake (George’s Mills, 0.1m -7m). This data has been QAQC’d to remove obviously errant data and artifacts of buoy maintenance visits.
Periphyton Productivity from the Shark River Slough and Taylor Slough, Everglades National Park (FCE LTER), South Florida, USA, October 2001 - October 2024
Periphyton productivity was measured annually at FCE LTER sites in Florida Bay and Shark Slough using light and dark BOD bottle incubations. Data are presented in terms of mass oxygen and/or carbon produced/consumed per gram of periphyton and per m2 of marsh. This is part of continuous data collection to test the hypothesis that phosphorus and nitrogen limit productivity at the upstream and downstream ends, respectively, of the FCE transects. Conclusions await longer-term data collection. Data collection is complete.

October 2001 surface water phytoplankton productivity for 10 Georgia Coastal Ecosystems LTER sampling sites
Water samples were collected by Niskin bottle or by hand from just beneath the surface during low tide surveys at or near 10 GCE-LTER sampling sites in October 2001. The incorporation of radiolabelled bicarbonate in response to varying levels of illumination was measured using a photosynthetron apparatus. Photosynthesis-irradiance (P-I) curves constructed from these measurements will be used in conjunction with algal biomass and PAR versus depth measurements to estimate instantaneous gross primary production in the water at each GCE sampling site. This study was part of the GCE-LTER hydrographic monitoring program, and will be repeated quarterly.
October 2001 surface water bacterial abundance at ten Georgia Coastal Ecosystems LTER sampling sites
Surface water samples were collected during low tide surveys near ten Georgia Coastal Ecosystem LTER sampling sites in October, 2001. Unfiltered subsamples were immediately preserved with buffered formalin and refrigerated for transport to the laboratory. The abundance of bacteria in each sample was determined using an epifluorescence microscope by counting DAPI-stained cells retained on a 0.2µm polycarbonate filter. This study was part of the GCE-LTER hydrographic monitoring program, and will be repeated quarterly.
October 2001 surface water dissolved organic carbon concentrations at ten Georgia Coastal Ecosystems LTER sampling sites
Water samples were collected by Niskin bottle from just beneath the surface during tidal surveys at ten GCE-LTER sampling sites in October, 2001. Water samples were immediately filtered through ashed Whatman GF/F filters and three replicate samples were acidified, refrigerated and transported to the laboratory for analysis. Concentrations of dissolved organic carbon were measured in each sample by high temperature combustion and chromatographic analysis using a Shimadzu TOC analyzer. This study was part of the GCE-LTER hydrographic monitoring program, and will be repeated quarterly.
October 2001 water column particulate carbon and nitrogen concentrations for Georgia Coastal Ecosystems LTER sampling sites
Water samples were collected from the surface and the bottom of the water column at ten GCE-LTER sampling sites and from the surface of the water column during six transect surveys along the Altamaha River in October, 2001. Samples were taken at various times of day and under various tidal conditions. The particulate matter was separated by filtration and analyzed for elemental carbon and nitrogen content by CN analysis. This study was part of the GCE-LTER hydrographic monitoring program, and will be repeated quarterly.
October 2001 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Doboy Sound transect
Five hydrographic surveys were performed between October 12 and October 14, 2001, along an east-to-west transect through Doboy Sound near Sapelo Island, Georgia (Doboy Sound Transect, GCE-DB). Vertical CTD profiles were collected at approximately 2km intervals from 0km to 12km along the transect during low tide and high tide conditions. Conductivity, temperature, pressure and optical backscatter were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected on the upcast were deleted, and the remaining data were averaged within 0.5m depth bins and interpolated to produce a smooth profile for contouring. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.
October 2001 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Intracoastal Waterway transect
Five hydrographic surveys were performed between October 11 and October 16, 2001, along the Intracoastal Waterway between the Altamaha River south of Wolf Island and Sapelo Sound (Intracoastal Waterway Transect, GCE-IC). Vertical CTD profiles were collected at approximately 1-3km intervals from -15km to 29km along the transect during various tidal regimes. Conductivity, temperature, pressure and optical backscatter were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected on the upcast were deleted, and the remaining data were averaged within 0.5m depth bins and interpolated to produce a smooth profile for contouring. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.
Soil salinity and organic content at GCE-LTER vegetation monitoring plots in October 2009
Soil samples were collected in conjunction with Fall 2009 plant monitoring at half of the permanent vegetation monitoring plots in the creekbank and midmarsh zones at 10 GCE study sites. Pore-water salinity was determined by analysis of supernatant salinity in dried soil samples hydrated with a measured volume of deionized water. Organic content was measured gravimetrically by comparing ash-free dry weight and total weight of soil samples.
Soil salinity and water content at GCE-LTER vegetation monitoring plots in October 2010
Soil samples were collected in conjunction with Fall 2010 plant monitoring at half of the permanent vegetation monitoring plots in the creekbank and midmarsh zones at 10 GCE study sites. Pore-water salinity was determined by analysis of supernatant salinity in dried soil samples hydrated with a measured volume of deionized water.
October 2001 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Inner Marsh transect
Five hydrographic surveys were performed between October 11 and October 16, 2001, along the Darien River, North River, and north channel of the Altamaha River (Inner Marsh Transect, GCE-IM). Vertical CTD profiles were collected at various nominal stations along the transect during flood and ebb tidal regimes. Conductivity, temperature, pressure and optical backscatter were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected on the upcast were deleted, and the remaining data were averaged within 0.5m depth bins and interpolated to produce a smooth profile for contouring. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.
