Stream restoration constrains fine particle retention within the hyporheic zone of urban streams

Stream restoration goals include reducing erosion and increasing hyporheic exchange to promote biogeochemical processing and improve water quality.  Suspended fine particles (&lt;100 µm) exchange with transient storage areas near and within streambeds and banks.  Fine particle deposition and retention directly impact carbon and nutrient cycling by supporting benthic and hyporheic metabolism, but accumulation of fine-particle deposits can impair metabolism by burying benthic biofilms and reducing streambed permeability.  Little is known on how fine particle dynamics respond to stream restoration.  We analyzed the transport and retention of water and fine particles at both the reach- and local-scale in a restored urban stream, 9 years post restoration.  We injected a conservative solute and fine particle tracers under summer baseflow conditions and monitored the distribution of tracers between surface water, porewaters, and transient storage areas including biofilms, hyporheic zones, and slowly moving surface waters.  Comparison of the results to a nearby unrestored stream demonstrate that the restored reach had an order of magnitude greater exchange of fine particles with transient storage zones, but 50% smaller rate of net particle immobilization.  At the local-scale, particle immobilization in the hyporheic zone of both streams was similar, suggesting that restoration increased fine particle exchange with storage areas, but did not increase long-term particle retention.  These results suggest that restoration structures successfully induced hyporheic exchange and maintained open pore spaces within the hyporheic sediments.  However, the limited retention of particulate organic matter may reduce hyporheic biogeochemical processing by not providing sufficient organic carbon for heterotrophic microbial metabolism.

Raster of unique PRISM IDs in the conterminous United States

This metadata record describes a raster of unique PRISM (Parameter-elevation Relationships on Independent Slopes Model) identifier (PRISMID) values. The data are in ESRI's ArcInfo ASCII raster format, a non-proprietary text interchange format.  PRISM climate data produced by the PRISM group at Oregon State University, such as time series of monthly precipitation and temperature, can be linked to the raster via the unique PRISMID values. In addition, model-estimated water budget components--including runoff (streamflow per unit area), evapotranspiration, snowfall and soil moisture storage--can be linked to the PRISM raster.

Nonindigenous aquatic species and potential spread after Hurricane Harvey-revised map

This refined map was created to help assess possible spread of nonindigenous aquatic species distributions due to flooding associated with Hurricane Harvey. Storm surge and flood events can assist expansion and dissemination of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of possible new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general area of the 2017 Hurricane Harvey flooding.

Chesapeake Bay Nontidal Network 1985-2014: Annual Loads

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2014. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the NTN watersheds.  To determine the trend in loads, the annual load results are flow normalized to integrate out the year-to-year variability in river discharge.  The trend in load is derived from the  flow-normalized load timeseries and represents the change in load resulting from changes in sources, delays associated with storage or transport of historical inputs, and (or) implemented management actions.

Chesapeake Bay Nontidal Network 2005-2014: Average Yields

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the nine Chesapeake Bay River Input Monitoring (RIM) stations for the period 1985 through 2015. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  Yields (represents the mass of constituent transported from a unit area of a given watershed)  are used to compare the export loads from one basin to another.  Yield results are obtained by dividing the annual load (pounds) of a given constituent by the respective watershed area (acres) from which the constituent was transported.  Yield results presented represent the average annual per-acre loads of nitrogen, phosphorus, and suspended sediment exported from each of the Chesapeake Bay nontidal network stations for the period 2005-2014.

Benthic infaunal communities of Baltimore and Norfolk canyons

Submarine canyons are morphologically complex systems, acting as major conduits of organic matter along continental shelves, promoting gradients in food resources, habitat heterogeneity, and areas of sediment resuspension and deposition. Often environmental conditions within canyons can be highly distinct, particularly in different parts of the canyon and in contrast to adjacent slopes. Here we examine how biogeochemical drivers shape the differences between canyon and slope infaunal communities in Baltimore and Norfolk Canyons in the U.S. Mid-Atlantic Region.  Specific comparisons included macrofaunal communities in Norfolk canyons and adjacent slope, hard substrate associated macrofaunal communities in Norfolk Canyon, macrofaunal communities associated with chemosynthetic habitats (e.g., microbial mats and mussel beds) near Baltimore and Norfolk Canyon, and meiofaunal communities in Baltimore Canyon and the adjacent slope. Replicate sediment cores were collected in each habitat and assessed for infaunal abundance, diversity, and community composition in relation to sediment biogeochemical parameters, including grain size, organic content, stable isotopes, and chlorophyll a. Canyon macrofaunal and meiofaunal communities exhibited differences in abundance, diversity, and community assemblages within the canyon in contrast to the slope, in relation to enrichment patterns of organic matter within the canyon. Chemosynthetic communities differed between habitat types, with microbial mat habitats exhibiting high density but low diversity communities. Macrofaunal communities associated with hard substrates had higher diversity than canyon axis communities and significantly contribute to the overall canyon biodiversity. This study provides a complete benthic infaunal appraisal of two canyon systems in the western Atlantic, highlighting the importance of canyons and their associated environments to host unique ecosystems, enhancing our understanding of the drivers of communities in submarine canyons, and providing regional baseline information for nearby canyon and chemosynthetic systems.

Productivity of Brown Pelican in the northern Gulf of Mexico (2014-2015)

The Brown Pelican (Pelecanus occidentalis) is a large-bodied seabird that nests in colonies of 10 to upwards of 5,000 pairs, on nearshore barrier islands in subtropical and tropical North American waters. It breeds between March and August, laying 2–3 eggs and raising 1–2 chicks per year. The species is facultatively migratory during nonbreeding, with some individuals remaining resident and others leaving breeding areas. Pelicans forage in near- and offshore waters and capture schooling fish by plunge-diving. 
This dataset serves as a record of field notes used to estimate Brown pelican fledging success in 8 breeding colonies in Texas (2014), and Alabama and the Florida Panhandle (2015). We visited nesting colonies from late incubation to fledging and recorded nest content in 3-4 focal groups per colony, each group containing 20 – 30 nests. Once nestlings reached 3 – 4 weeks of age, we banded nestlings on the right tarsus with a metal and on the left tarsus with a permanent plastic band engraved with a unique three-digit white alphanumeric code. Once nestlings began to disperse away from nest locations (typically ca. 30 days post-hatch), we searched the surrounding areas of the colony with binoculars for banded chicks and recorded all bands observed. Beginning approximately 8 weeks after hatch, we also searched the colony every 3 – 5 days for banded chicks that had died, and recovered all bands found. Detailled methods may be found in the associated publication.

This dataset summarizes proximate density values for common prey species of Brown Pelican, collected from 2013-2014 in the Northern Gulf of Mexico at 10 breeding colonies from Texas to the Florida Panhandle. We measured proximate composition and energy density of common prey species using methods as described by Anthony et al. (2000, Lipid content and energy density of forage fishes from the northern Gulf of Alaska). We extracted lipids and proteins from regurgitated purchased fish samples. We multiplied the lipid and protein contents of each sample by standard energetic values based on their relative assimilation efficiencies (lipids: 39.5 kJ/g; proteins: 17.8 kJ/g: Schmidt-Nielsen 1997, Animal Physiology: Adaptation and Environment) to obtain the overall energy density of the sample. Detailed methods may be found in the associated publication.
