Habitats along migratory routes may provide key resources for migratory species (e.g. stopover habitat). For example, migratory juvenile salmon transit through estuaries on their way from freshwaters out to the ocean, but they may also reside and feed in these habitats. Here we examined the amount of time that juvenile salmon feed and reside in the estuary of the Skeena River (British Columbia,...

Speciation and reactivity of mercury were examined in Berry's Creek estuary downstream of a highly mercury-contaminated U.S. EPA Superfund site during the summers of 2002 and 2003. Surface water samples from Berry's Creek estuary, its confluence with the Hackensack River, and upstream of that confluence were analyzed for total (THg), particulate (PHgT), and dissolved (DHg) mercury, total and pa...

Monitoring sediment quality and total mercury concentrations over the period 1993-2001 at 26 stations in San Francisco Estuary has shown the seasonal cycling of mercury sediment concentrations, as well as a significant (P < 0.05) decrease in those concentrations at eight stations across the estuary. This decrease in sediment mercury concentrations is attributed to the transport of relatively cl...

About this Report This publication represents a new style of reporting for the San Francisco Estuary Regional Monitoring Program (RMP). The fundamental purpose of the RMP is to provide information to improve the management of the San Francisco Estuary and protect what we value about the Estuary (SFEI 1998a). The intent of The Pulse of the Estuary (hereafter referred to as The Pulse) is to help ...

Many tidal influenced estuaries and coastal basins feature amplification because of, e.g., convergence reflection. Increasing rates were observed in the Elbe estuary, with consequences for construction measures, nautical manoeuvring, flood protection, riverbed morphology ecosystems. Although many studies conducted investigating wave transformation estuaries, based on spatially well-distributed ...

Household survey data and spatially explicit Sentinel-2 satellite images of land cover use during the dry wet seasons were used to investigate livelihood strategies in Lower Tana River Delta Kenya, where food security economic activity rely almost exclusively on ecosystem goods services. Land classification imagery successfully showed seasonal changes estuary-related vegetation habitats from wh...

The Pearl River, with an annual mean discharge rate of ~ 10,000 ms, has profound dynamic and ecological influences on the northern shelf of the South China Sea. A coastal ocean model is set up to simulate the circulation in the Pearl River Estuary and the neighboring coastal regions. In winter the Guangdong Coastal Current, which flows southwestward and passes the mouth of the estuary, forces t...

The black-chinned tilapia Sarotherodon melanotheron is a marine teleost characterised by an extreme euryhalinity. However, beyond a certain threshold at very high salinity, the species exhibits impaired growth and precocious reproduction. In this study, the relationships between reproductive parameters, environmental salinity and condition factor were investigated in wild populations of this sp...

Ecosystem function measurements can enhance our understanding of nitrogen (N) delivery in coastal catchments across river and estuary ecosystems. Here, we contrast patterns of N cycling and export in two rivers, one heavily influenced by wastewater treatment plants (WWTP), in a coastal catchment of south Texas. We measured N export from both rivers to the estuary over 2 yr that encompass a seve...
