PIE LTER zooplankton surveys using plankton tows along transects in the Plum Island Sound estuary, Massachusetts

Anne Giblin, Peter Milligan, Charles Hopkinson & Plum Island Ecosystems LTER
Zooplankton were collected in spring and late summer/fall at four stations representing the salinity gradient in the Parker River-Plum Island Sound estuary. Two size classes, greater than 335 micron and greater than 150 micron, were collected by net tows. Conductivity or salinty and temperature were recorded for each sample. Samples were concentrated to less than 250 mls and preserved in 70 percent EtOH. For taxonomy, sample splits were taken such that a minimum of 250...

Macrosystems EDDIE Module 2: Cross-Scale Interactions

Cayelan C. Carey & Kaitlin J. Farrell
Environmental phenomena are often driven by multiple factors that interact across space and over time. In freshwater lakes and reservoirs worldwide, phytoplankton blooms are increasing in frequency and severity due to interactions between local, regional, and continental drivers, including land use (local) and climate change (regional) drivers. Because it is difficult to predict how phytoplankton blooms will respond to the different aspects of land use and climate change simultaneously, many researchers are using lake simulation...

CCE LTER process cruise, in the California Current region, event log records including date, time, position and activity for use in post-cruise data integration based on co-sampling indexes, 2006 - 2017 (ongoing).

California Current Ecosystem LTER
The event logger program developed and maintained by the California Cooperative Oceanic Fisheries Investigations, SIO, program is used aboard CCE LTER process cruises to create indexes with temporal, spatial and activity information for post-cruise data integration. The event log is configured aboard the ship for the recording of sampling events by both ship crew personnel on the bridge, and research personnel in the lab. The event log is processed post-cruise to correct for various errors.

Mound Stage Data for mounds in Alabama, Georgia, Mississippi, and Tennessee

Coweeta Long Term Ecological Research Program & David J. Hally
These data provide mound counts, listing of stages, and associated time periods for Precolumbian Native American earthen mound sites in four states in the southeastern United States. Each row represents a single mound. Official State Site Numbers are provided with each row to link the data back to state archaeological site file data. Coordinate data are not available as prescribed by law. Coordinate data should be available from state archaeological site file offices, but only...

Oxygen Flux in a Restored Seagrass Meadow on the Coast of Virginia, 2011-2012

Jennie Rheuban, Peter Berg & Karen McGlathery
Oxygen flux was measured seasonally using the eddy correlation technique in a restored eelgrass (Zostera marina L.) meadow in the Virginia coastal bays (USA). In 5 intensive field campaigns, we covered seasonal variation in oxygen metabolism and biomass with overlap in late summer to observe interannual variability.

Precipitation data for D1 chart recorder, 1964 - ongoing.

Jennifer F Morse & Mark Losleben
Precipitation data were collected on a daily time-scale from the D1 climate station (3743 m) since 1964. Over time, various circumstances have led to days with missing values. Some of these values were estimated from nearby climate stations.

Precipitation data for C1 chart recorder, 1952 - ongoing.

Jennifer F Morse & Mark Losleben
Precipitation data were collected on a daily time-scale from the C1 climate station (3018 m) since 1952. Over time various circumstances have led to days with missing values. Some of these values were estimated from nearby climate stations.

Soil texture for Saddle Stream Network, 2017

Anna L Hermes
Soil texture is an important hydrologic control. To measure soil texture across the Niwot Ridge LTER Saddle Stream Catchment, surface (0 – 10 cm) soil samples (n = 84) were collected on roughly a 60 x 60 m grid, including sensor network sites. After drying and sieving to less than 2mm, soil size fractions (percent sand, silt, and clay) and corresponding soil texture were determined by laser particle size analysis. Soil size fractions and texture...

Soil moisture and temperature surveys for Saddle Stream Network, 2017

Anna L Hermes
Surface soil moisture and temperature reflect patterns in snowmelt and hydrologic connectivity in alpine ecosystems. In the summer of 2017, surface soil moisture and temperature were measured on eight surveys at 84 locations in the Niwot Ridge Saddle Stream catchment. The eight surveys were July 3, 2017 – September 9, 2017. Overall, soil moisture showed the influence of snowmelt early in the season and equilibration of soil moisture during the summer monsoon. Seasonal patterns in...

Saturated and unsaturated hydraulic conductivity for Saddle Stream Network, 2017

Anna L Hermes
Saturated and unsaturated hydraulic conductivity are important surface hydrologic properties that dictate the how fast water moves into the subsurface. Saturated and unsaturated hydraulic conductivity were measured at approximately 25 locations throughout the Niwot Ridge Saddle Stream Catchment in 2017. Saturated hydraulic conductivity was calculated from saturated infiltration rates determined using a single-ring infiltrometer. Unsaturated hydraulic conductivity was calculated from unsaturated infiltration rates determined using a mini-disk portable tension infiltrometer. Both measurements had over an...

Soil loss on ignition for Saddle Stream Network, 2017

Anna L Hermes
Soil loss on ignition (LOI), as a proxy for total soil organic matter, is an important control on surface hydrology. To measure soil LOI across the Niwot Ridge LTER Saddle Stream Catchment, surface (0 – 10 cm) soil samples (n = 84) were collected on roughly a 60 x 60 m grid, including sensor network sites. After drying, sieving to < 2mm, and grinding to a fine powder, a ~20 g subsample of soil was...
