Our overarching questions are: (1) How much of the river water and water-borne constituents (i.e. sediment, nutrients, organic matter) from the Jago, Okpilak and Hulahula rivers are coming from glacier melt? (2) How do inputs from these rivers affect the downstream ecosystems? (3) How will loss of glaciers affect these ecosystems? The study will help elucidate how inputs from glacier-dominated arctic rivers differ from unglaciated rivers, through a combination of ground work, boat work, and remote sensing. In Phase One of this study, we intend to explore the relationship between glaciers and coastal ecosystems. Our goal in this phase-one study is not to answer these questions conclusively but rather improve our...
The presence of salinity in shallow waters influences living resources and habitats within Gulf of Mexico estuaries. The salinity gradient is widely recognized as foundational in maintaining biological diversity and productivity of estuaries. A clear understanding of the factors controlling salinity and its variability in estuarine surface waters is essential for proper stewardship and for sustaining ecological structure and function. Salinity data are collected by numerous Federal, State, and local agencies and universities as part of routine data-collection programs. The U.S. Geological Survey compiled salinity data from existing online databases – all water samples were collected in Gulf of Mexico estuaries....

This paper explores the impacts of shrinking glaciers on downstream ecosystems in the Arctic National Wildlife Refuge. Glaciers here are losing mass at an accelerating rate and will largely disappear in the next 50–100 years if current trends continue. We believe this will have a measurable and possibly important impact on the terrestrial and estuarine ecosystems and the associated bird and fish species within these glaciated watersheds.

The St. Petersburg Coastal and Marine Science Center is one of three science centers that conduct research within the USGS Coastal and Marine Hazards Research Program. The USGS St. Petersburg Coastal and Marine Science Center has a primary focus of investigating processes related to coastal and marine environments and their societal implications related to natural hazards, resource sustainability, and environmental change.

Estuaries are located at the interface where rivers meet the sea, creating unique ecosystems with complex physical and biological processes. Coastal wetlands provide essential ecosystem services to people, including flood protection from high tides and storm surges, commercial fisheries, carbon sequestration, improved water quality, and wildlife food and habitat. Coastal wetlands are also home to hundreds of migratory and resident wildlife species including threatened and endangered species of management concern. Wetlands also have the unique ability to increase their elevation relative to sea-level rise, therefore protecting nearby communities from flooding. In California, prolonged drought and extreme storm events...

Coastal wetland ecosystems are expected to migrate landward in response to accelerated sea-level rise. However, due to differences in topography and coastal urbanization extent, estuaries vary in their ability to accommodate wetland migration. The landward movement of wetlands requires suitable conditions, such as a gradual slope and land free of urban development. Urban barriers can constrain migration and result in wetland loss (coastal squeeze). For future-focused conservation planning purposes, there is a pressing need to quantify and compare the potential for wetland landward movement and coastal squeeze. For 41 estuaries in the northern Gulf of Mexico (i.e., the USA gulf coast), we quantified and compared...

Problem Dissolved oxygen (DO) is an important indicator of water quality that until recently has been cost-prohibitive to monitor extensively in both space and time. Continuous water-quality data, particularly in coastal environments with bidirectional tidal flow, is necessary for resource managers to understand the dynamic changes in water quality that occur tidally, daily, seasonally, and during aperiodic events. In the estuaries surrounding Long Island, such events may include wastewater treatment plant failures, harmful algal blooms, and extreme weather. The U.S. Geological Survey (USGS) has extensive experience with continuous water-quality monitoring at fixed locations along the coast that provides valuable...

The NFHAP Coastal Spatial Framework and Indicator Datasets consist of a geospatial base layer developed in ArcGIS, and associated data fields joined to the spatial framework. The Coastal Spatial Framework is a layer of 612 distinct polygons covering coastal areas of the Continental U.S. Polygons represent either coastal watersheds (land) or coastal waters (estuaries, inshore marine, offshore marine),and are classified into six regions and 22 nested subregions. Each polygon is assigned a unique code (UniqueID) to provide location reference for indicator data, and enable joins to separate data tables.s for information recorded in the Bibliography and Assessment tables. Key indicator data fields attributed to each...

This data set is comprised of five files related to the modification and scoring of Index of Waterbird Community Integrity (IWCI) scores for all waterbirds of the Chesapeake Bay. One Excel file (A) contains a list of 100+ Chesapeake waterbird species and their species attribute and IWCI scores. Another Excel file (B) contains case study data from recent surveys of breeding and migratory waterbirds in Chesapeake Bay and shoreline delineations across a disturbance gradient that were used to demonstrate the utility of the modified index. Finally, three supplemental files include an Access database (C), R code (D) and a protocol (E) for running the complex steps to calculate index scores.

This dataset is comprised of six files related to waterbird surveys and resulting Index of Waterbird Community Integrity (IWCI) scores in 21 subestuaries of the Chesapeake Bay from 2010-2014. Two .csv files (1 data file: Prosser et al 2017_IWCI Results MS_Bird Survey Raw Data.csv, 1 definitions file: Prosser et al 2017_IWCI Results MS_Bird Survey Raw Data_Definitions.csv) contain data related to raw waterbird survey data from two seasons (summer and fall). Two .csv files (1 data file: Prosser et al 2017_IWCI Results MS_Species List.csv, 1 definitions file: Prosser et al 2017_IWCI Results MS_Species List_Definitions.csv) contain data related to 60+ Chesapeake waterbird species observed in surveys and their species...

The South Florida Fish and Invertebrate Assessment Network (FIAN) is a monitoring project within the Comprehensive Everglades Restoration Plan (CERP). It is an element of the Southern Estuaries module of the Monitoring and Assessment Plan (MAP).The FIAN is designed to support the four broad objectives of MAP: (1) to establish a pre-CERP reference state, including variability, for each of the performance measures; (2) to determine the status and trends in the performance measures; (3) to detect unexpected responses of the ecosystem to changes in stressors resulting from CERP activities; and (4) to support scientific investigations designed to increase ecosystem understanding, cause-and-effect, and interpretation...

Coastal resource managers are faced with many challenges and uncertainties in planning adaptive strategies for conserving estuarine habitats with climate change. To plan and manage for future scenarios, managers need access to data, models, and training on the best-available science. To address this need, the USGS Western Ecological Research Center has worked with federal, Tribal, state, and local partners to establish a network of study sites in 17 estuaries along the Pacific Coast, examining the climate change effects on tidal wetlands with high-quality local data, downscaled models, and projected storm effects. Study sites include ten USFWS National Wildlife Refuges and four NOAA National Estuarine Research Reserves.
