Past and present sea levels in the Chesapeake Bay Region, USA
In a new article for GSA Today, authors Benjamin DeJong and colleagues write that sea-level rise (3.4 mm/yr) is faster in the Chesapeake Bay region than any other location on the Atlantic coast of North America, and twice the global average (1.7 mm/yr). They have found that dated interglacial deposits suggest that relative sea levels in the Chesapeake Bay region deviate from global trends over a range of timescales. (2015-07-28)

New study reveals biodiversity important at regional scales
New research shows that biodiversity is important not just at the traditional scale of short-term plot experiments--in which ecologists monitor the health of a single meadow, forest grove, or pond after manipulating its species counts--but when measured over decades and across regional landscapes as well. The findings can help guide conservation planning and enhance efforts to make human communities more sustainable. (2021-02-11)

VIMS issues annual dead-zone report card for the Chesapeake Bay
An annual model-based report on low-oxygen conditions in Chesapeake Bay during 2018 indicates a total volume of 'hypoxic' waters very similar to the previous year, but with a dramatic drop in hypoxia during late July due to mixing by strong winds. The duration of hypoxia in 2018 was greater than in recent years. (2018-10-24)

Scientists are expecting that this year's Chesapeake Bay hypoxic low-oxygen zone, also called the 'dead zone,' will be approximately 1.37 cubic miles -- about the volume of 2.3 million Olympic-size swimming pools. While still large, this is 10 percent lower than the long-term average as measured since 1950. (2015-06-23)

Study shows invasive blue catfish can tolerate high salinities
A new study by researchers at the Virginia Institute of Marine Science warns that blue catfish -- an invasive species in several Chesapeake Bay tributaries -- tolerate salinities higher than most freshwater fishes, and thus may be able to expand their range downstream into mainstem Chesapeake waters, and from there into new Bay tributaries and even Delaware Bay. (2019-11-05)

Increased sediment and nutrients delivered to bay as Susquehanna reservoirs near sediment capacity
Reservoirs near the mouth of the Susquehanna River just above Chesapeake Bay are nearly at capacity in their ability to trap sediment. As a result, large storms are already delivering increasingly more suspended sediment and nutrients to the Bay, which may negatively impact restoration efforts. (2012-08-30)

Study finds water quality improvements in Maryland's Choptank River
The Chesapeake Bay has a long history of nutrient pollution resulting in degraded water quality.

(2021-01-26)

Smithsonian study: Sediment prediction tools off the mark
A recent study led by Smithsonian ecologist Kathy Boomer suggests it is time for a change in at least one area of watershed management. Boomer has been examining the tools scientists and managers use to predict how much sediment runs into the Chesapeake Bay, and by her account, they are way off the mark. The study, co-authored by SERC ecological modeler Donald Weller and ecologist Thomas Jordan, appears in the January/February issue of the Journal of Environmental Quality. (2008-01-29)

Harmful algal blooms in the Chesapeake Bay are becoming more frequent
A recent study of harmful algal blooms in the Chesapeake Bay and its tributaries by the University of Maryland Center for Environmental Science shows an increase in ecosystem-disrupting events in the past 20 years being fed by excess nitrogen runoff from the watershed. While blooms have long been a concern, this study is the first to document their increased frequency in the Bay. Similar events are happening around the world. (2015-05-11)

Warming climate could increase bacterial impacts on Chesapeake Bay shellfish, recreation
Researchers have found that three common species of Vibrio bacteria in Chesapeake Bay could increase with changing climate conditions by the end of this century, resulting in significant economic and healthcare costs from illnesses caused by exposure to contaminated water and consumption of contaminated shellfish. The study, the first to apply a new way of downscaling global climate models to the Chesapeake Bay, was conducted by NOAA scientists and colleagues and published in GeoHealth. (2017-09-26)

Protecting bays from ocean acidification
As oceans absorb more man-made carbon dioxide from the air, a process of ocean acidification occurs that can have a negative impact on marine life. But coastal waterways, such as Chesapeake Bay, can also suffer from low oxygen and acidification. New research from the University of Delaware identifies one way to protect these waterways -- the presence of submerged aquatic vegetation (SAV). (2020-06-12)
