Researchers Study the Effects of Harmful Algal Blooms

December 1, 2021 — The sample bottle came back from the river, over the gunwale, and into the boat. The water sample was a dark reddish-brown, like strong, steeped tea that you are unable to see through. Literally tens of thousands of algal cells made up every drop of the water sample. Back at the laboratory, scientists at the Virginia Institute of Marine Science (VIMS) will analyze the sample to determine the type and density of algal species in the water. The samples, taken from the York River in the Southern Chesapeake Bay allow scientists to study harmful algal blooms, also called HABs. According to NOAA’s National Centers for Coastal and Ocean Science, almost every state in the nation now experiences some kind of HAB event. The number of hypoxic water bodies in the United States has increased 30 fold since the 1960s, with more than 300 coastal systems now impacted.

As you might guess from the name, the tiny microscopic organisms making up HABs are algae, which are a very diverse group of organisms. Phytoplankton are a type of algae usually responsible for creating blooms. Most often, these phytoplankton are made up of an equally diverse group of organisms known as dinoflagellates, which can be found in both fresh and marine waters.

Blooms Occur Worldwide

HABs are a growing concern worldwide, occurring in the Gulf of Mexico and surprising places such as the Alaskan Arctic. Globally warming water temperatures, a result of our changing climate, is one reason blooms are occurring more frequently and over a global scale.

VIRGINIA: Dominion offshore wind farm cost climbs to $9.8B

November 8, 2021 — Dominion Energy Inc.’s offshore wind farm will cost about $2 billion more than expected, the Richmond-based Fortune 500 utility’s chair, president and CEO, Bob Blue, said during a third quarter earnings call Friday.

Instead of the previously estimated $7.8 billion, the 2.6-gigawatt Coastal Virginia Offshore Wind (CVOW) commercial project will cost approximately $9.8 billion, Blue said, attributing the roughly 25% cost increase to rising commodities expenses and general cost pressures across a number of industries right now amid mounting inflation. Additionally, Blue cited costs associated with the need to build about 17 miles of new transmission lines and other onshore infrastructure associated with the project.

Dominion plans to build the 180 wind-turbine farm 27 miles off the coast of Virginia Beach, with construction beginning in 2024. When completed in 2026, the wind farm is expected to power 660,000 homes. The wind farm will cost residential customers about $4 per month over the estimated 30-year lifespan of the wind farm, a Dominion spokesperson said.

Researchers map best conditions for forage fishes in the Chesapeake

October 28, 2021 — Big fish eat smaller fish, but only if there are smaller fish to eat. A new study led by researchers at William & Mary’s Virginia Institute of Marine Science maps the conditions most suitable for key species of forage fishes in the Chesapeake Bay, offering guidance for any future efforts to protect or restore the habitat required to yield sufficient prey for predatory fishes such as striped bass.

Lead author on the study, which appears in the October issue of Frontiers in Marine Science, is Dr. Mary Fabrizio, a professor and chair of Fisheries Science at VIMS. Co-authors are fellow VIMS researcher Dr. Troy Tuckey, along with Drs. Aaron Bever and Michael MacWilliams of Anchor QEA, LLC. Bever is a VIMS alum.

“Small fishes such as bay anchovy are important components of the diets of predatory fishes in Chesapeake Bay,” says Fabrizio, “but factors that affect local abundances of these  fish have been largely unexplored.”

To throw light on these factors, the research team set out to quantify and map suitable habitats for four common species of forage fishes in Bay waters, and to assess the relationship between habitat extent and fish abundance. In addition to bay anchovy, the forage species studied were juvenile spot, juvenile spotted hake, and juvenile weakfish.

The team based their study on data generated by counting the number of forage fishes caught in a trawl net during fishery surveys conducted by VIMS and the Maryland Department of Natural Resources between 2000 and 2016. These surveys sample at more than 100 sites throughout the Bay each month. They coupled these catch data with output from computer models simulating the environmental conditions at each sampling site. These conditions include water depth and temperature, salinity, stratification, dissolved-oxygen levels, and current speeds. The researchers also noted whether the bay floor beneath each net tow was sandy or muddy, and the distance to the nearest shoreline.

$200 million wind turbine facility planned for Virginia

October 26, 2021 — Gov. Ralph Northam (D) and executives from Dominion Energy and Siemens Gamesa Renewable Energy on Monday announced a $200 million project to finish building turbine blades that would harness offshore wind on 80 acres of the Portsmouth Marine Terminal.

A lineup of local, state and federal leaders said the project, the largest in the United States, positioned Virginia at the forefront of developing wind energy. “This puts us a vital step closer to being the leader in offshore wind,” Northam said, adding that in a few short years the state had pivoted from exploring offshore drilling, which would harm the environment, to offshore wind. “Virginia,” he said, “is all in for offshore wind.”

The facility, combined with its operations and maintenance activities, will create 310 new jobs, including 50 service positions to support Dominion’s Coastal Virginia Offshore Wind Project 27 miles off the coast. Dominion says the wind farm will generate enough electricity to power up to 660,000 homes at peak and avoid as much as 5 million tons of carbon dioxide being dumped into the atmosphere annually.

On the water, a different view of menhaden fishing

October 26, 2021 — In his recent op-ed (“Fish spills renew concerns about menhaden management,” Oct. 2), the Chesapeake Bay Foundation’s Chris Moore gives readers a picture of a menhaden fishery that I and my crew do not recognize.

I’ve fished menhaden here in Virginia for most of my life. The view of the fishery expressed by Moore and the CBF of a distant Canadian conglomerate that doesn’t care about the health of the bay or the future of this fishery, could not be further from the truth. It is ignorant and insulting to hundreds of hard-working, blue-collar menhaden fishermen.

Much has been made, both in Moore’s op-ed and elsewhere, of the fact that Omega Protein, Virginia’s oldest and largest fishing company, now has a Canadian parent company. But menhaden fishing has been a Virginia institution since 1878, and there has been a menhaden fishery operating out of Virginia’s Northern Neck continuously since then. I’m a local, my crew are all locals, and many of them come from African American families who have fished menhaden for generations. The majority of these families have been fishing in Virginia long before CBF has even existed.

A corporate address in Canada does not erase the deep Virginia roots of this fishery and the fishermen who are part of it.

Virginia’s striped bass forecast looks stable as juvenile numbers hold steady

October 20, 2021 — Juvenile striped bass numbers are holding steady in Virginia’s Chesapeake Bay tributaries, the latest annual survey by the Virginia Institute of Marine Science found.

But a parallel survey in Maryland waters showed below-average numbers.

The surveys look at striped bass that hatched in the spring and that will be large enough to catch, legally, in three to four years.

Preliminary results of the Virginia survey showed an average of 6.3 fish for each haul of a seine net in the James, York and Rappahannock rivers. These young striped bass usually measure between 1.5 and 4 inches. That’s the 9th consecutive year of average or above average results, VIMS said.

Maryland Striped Bass Survey Below Average for 3rd Year

October 19, 2021 — Maryland’s juvenile striped bass survey finds rockfish reproduction is below average for the third year in a row, continuing a worrisome trend. Virginia’s survey, meanwhile, shows a nine-year streak of average or above-average reproduction.

Both states conduct surveys of young-of-year striped bass to track reproductive success of the Bay’s treasured fish. The Maryland Department of Natural Resources (DNR) reports an index of 3.2 in the 2021 survey, which remains well below the long-term average of 11.4.

DNR is optimistic, saying in a press release, “The coastal striped bass population has decreased in size, but is still capable of strong reproduction with the right environmental conditions. Variable spawning success is a well-known characteristic of the species.”

They do acknowledge that the below-average numbers “are a concern”. In 2019 the Atlantic States Marine Fisheries Commission (ASMFC) determined the striped bass species was being overfished, and set new limits for East Coast states to follow. Still, some environmental groups and even anglers feel that states like Maryland should be doing more.

Port of Virginia Expands Dominion Energy Lease to Create Wind Port

August 27, 2021 — The Port of Virginia reached an agreement to lease a dramatically increased portion of the Portsmouth Marine Terminal to Dominion Energy. The agreement, which positions the port to become a leader in the emerging offshore wind energy sector, puts to use an idle terminal area converting it into a large pre-assembly and staging area for the planned wind farm off the Virginia coast. Previously, the port had agreed to a lease to create a small staging area.

Under the new agreement, Dominion Energy will use 72 acres of the deep-water, multi-use marine cargo Portsmouth Marine Terminal as a staging and pre-assembly area for the foundations and turbines that will be installed 27 miles off the coast of Virginia Beach. Expected to be in service by the mid-decade, the Virginia wind project will produce more than 2,600 megawatts of renewable energy.

“This announcement is yet another milestone toward making Virginia the national leader in offshore wind power,” said Governor Ralph Northam. “The Commonwealth and Dominion Energy are standing together to promote clean energy, reduce carbon emissions, create jobs, and build a new American industry on the East Coast of the United States.”

The lease term is 10 years—valued at nearly $4.4 million annually—and includes an option for two five-year renewals. In January 2020, Virginia had agreed to a lease for 1.7 acres at the Portsmouth Marine Terminal through 2026, with options to expand to 40 acres. The original plan called for the terminal to operate solely as a staging area.
