Chesapeake Bay Dissolved Oxygen Criterion Attainment Deficit: Three Decades of Temporal and Spatial Patterns

Frontiers in Marine Science, 2018
Low dissolved oxygen (DO) conditions are a recurring issue in waters of Chesapeake Bay, with detrimental effects on aquatic living resources. The Chesapeake Bay Program partnership has developed criteria guidance supporting the definition of state water ...

The competing impacts of climate change and nutrient reductions on dissolved oxygen in Chesapeake Bay [PDF]

Biogeosciences, 2018
The Chesapeake Bay region is projected to experience changes in temperature, sea level, and precipitation as a result of climate change. This research uses an estuarine-watershed hydrodynamic–biogeochemical modeling system along with projected mid ...

Spatial and temporal variation in the occurrence of bottlenose dolphins in the Chesapeake Bay, USA, using citizen science sighting data.

PLoS ONE, 2021
Bottlenose dolphins (Tursiops truncatus) are migratory marine mammals that live in both open-ocean and coastal habitats. Although widely studied, little is known about their occurrence patterns in the highly urbanized estuary of the Chesapeake Bay, USA ...

Composition and temporal patterns of larval fish communities in Chesapeake and Delaware Bays

Frontiers in Marine Science, 2015
Comparing larval fish assemblages in different estuaries provides insights about the coastal distribution of larval populations, larval transport, and adult spawning locations (Ribeiro et al. 2015).

High salinity tolerance of invasive blue catfish suggests potential for further range expansion in the Chesapeake Bay region.

PLoS ONE, 2019
In estuaries, salinity is believed to limit the colonization of brackish water habitats by freshwater species. Blue catfish Ictalurus furcatus, recognized as a freshwater species, is an invasive species in tidal rivers of the Chesapeake Bay.

The Extent of Seasonally Suitable Habitats May Limit Forage Fish Production in a Temperate Estuary

Frontiers in Marine Science, 2021
The sustained production of sufficient forage is critical to advancing ecosystem-based management, yet factors that affect local abundances and habitat conditions necessary to support aggregate forage production remain largely unexplored.

Satellite Telemetry Reveals Spatial Overlap Between Vessel High-Traffic Areas and Humpback Whales (Megaptera novaeangliae) Near the Mouth of the Chesapeake Bay

Frontiers in Marine Science, 2020
During winter months, humpback whales (Megaptera novaeangliae) frequent the coastal waters of Virginia near the mouth of the Chesapeake Bay. Located within the Bay is Naval Station Norfolk, the world’s largest naval military installation, and the Port of

Differences in fouling community composition and space occupation across broad spatial and temporal scales

Frontiers in Marine Science, 2022
Sessile marine invertebrate (biofouling) communities have served as an important model in ecology for evaluating fundamental patterns and processes, including invasion dynamics, which vary at broad spatial and temporal scales.

Investigating effects of the aloeVR technology on the HRV and emotion regulation of middle schoolers with learning disabilities

Discover Education
Self-regulation, which subsumes variables like emotional and behavioral regulation is usually measured using self-report and qualitative techniques, but biomarkers like heart rate variability (HRV) are also indicative of self-regulation.
