Slightly smaller-than-average dead zone predicted for Chesapeake Bay

Scientists expect low river flow and reduced nutrient-rich runoff from the Susquehanna and Potomac Rivers this spring to result in an average to slightly smaller-than-average dead zone in the main stem of the Chesapeake Bay this summer.

When nutrient-fueled algae blooms die and decompose, they result in areas of little to no oxygen, known as dead zones.

Aquatic life—from blue crabs to underwater grasses—relies on dissolved oxygen to survive. When nutrient-fueled algae blooms die and decompose, the resulting areas of little to no oxygen, known as dead zones, can suffocate underwater plants and animals. The latest forecast predicts a mid-summer hypoxic, or low-oxygen, zone of 1.58 cubic miles: close to the long-term average. The anoxic, or no-oxygen, zone is expected to reach 0.28 cubic miles in early summer and grow to 0.31 cubic miles by late-summer.

This forecast, funded by the National Ocean and Atmospheric Administration (NOAA), is based on models developed at the University of Maryland Center for Environmental Science and the University of Michigan and relies on estimated nutrient loads from the U.S. Geological Survey (USGS). According to USGS, 66.2 million pounds of nitrogen entered the Chesapeake Bay in from January to May 2016, which is 17 percent lower than average nitrogen loadings.

Over the next few months, researchers with the Maryland Department of Natural Resources (DNR) and the Virginia Department of Environmental Quality (DEQ) will monitor oxygen levels in the Bay, resulting in a final measurement of the Bay’s dead zone later this year.

‘Sneaker index’ of 31 inches measured at Bernie Fowler Wade-In

Former Maryland State Senator Bernie Fowler saw his sneakers through 31 inches of water at the 29th annual Patuxent River Wade-In on June 12. High winds and rough waters meant this year’s “sneaker index”—the deepest point at which Fowler can still see his shoes as he wades into the water—measured far lower than 2015’s 44.5 inches.

Bernie Fowler, a former Maryland state senator and long-time advocate for a healthy Patuxent River, leads last year's 28th annual Patuxent River Wade-In on June 14, 2015.

Since 1988, the now 92-year-old Fowler—clad in his signature white sneakers—has held the wade-in on the second Sunday in June, to bring attention to the polluted waters of the Patuxent River and the Chesapeake Bay. The event moved to Jefferson Patterson Park and Museum in 2010 after decades on Broomes Island.

In his youth, Fowler could wade into the Patuxent up to his chest and still see fish, shellfish and underwater grasses. But nutrient and sediment pollution in the river have led to degraded water clarity and fueled algae blooms that block sunlight from reaching the river bottom. The 1960s sneaker index of 57 inches now serves as the benchmark for a restored Patuxent River.


Humans of the Chesapeake: Earle Peterson

Earle Peterson stands on a dock facing Cranberry Bog, a pristine 70-acre wetland, at Greenwoods Conservancy in Otsego County, N.Y., on May 23, 2015.

Earle Peterson of Cooperstown, New York, owns the nearly 1,200 acres of land that make up The Greenwoods Conservancy. Peterson works with the Otsego Land Trust to permanently preserve the land, ensuring that it will serve as an educational, aesthetic and environmental resource for the surrounding community for years to come.

With Peterson behind the wheel of his old pickup truck, he took our photographer on a tour of Greenwoods on a spring day last year. Passing a roadside pond, he observed a couple of Canada geese.

“These aren’t corporate geese—these are wild ones,” Peterson said. “Now these same geese could very well winter in Chesapeake—and follow the river from beginning to end.”

As the truck bounced over dirt and gravel roads, the conversation shifted to the Susquehanna River, and Peterson was succinct in his thoughts, as someone who lives much closer to its headwaters in Cooperstown than its mouth in Havre de Grace, Maryland.

“It isn’t just that wide expanse down there,” Peterson said.

Assessment offers look at resiliency of Maryland’s shorelines

A new Coastal Resiliency Assessment from the Maryland Department of Natural Resources and The Nature Conservancy of Maryland & D.C. will help state and local decision-makers focus conservation and restoration activities on coastal communities that are most at risk of flooding, erosion, sea level rise and other hazards.

More than 7,000 miles of shoreline make up Maryland’s coast—which borders both the Chesapeake Bay and the Atlantic Ocean—and these areas are particularly vulnerable to rising sea levels, severe storms and erosion. The Coastal Resiliency Assessment worked to identify regions that are most at risk, existing natural lands that can provide protection and key places to target conservation and restoration efforts. According to the study, habitats like forests and wetlands currently protect 22 percent of the state’s coastal areas and their communities.

The assessment has been incorporated into the Maryland Coastal Atlas—an interactive hub of ocean, estuary and shoreline spatial data—so planners can identify high-priority areas for projects. Data found in the assessment includes an index of high-, moderate- and low-hazard shorelines; places where habitat plays a role in risk reduction; communities at risk of flooding; areas where existing marshes could provide coastal protection; and priority shorelines for conservation and restoration projects.
