algae bloom

Nanticoke Wastershed Alliance

A new report by the Nanticoke Watershed Alliance found that the region is still suffering from high amounts of nitrogen.

In its new report Beth Wasden, volunteer and outreach coordinator with the Alliance, said there were some improvements in many of the sub-watersheds.

But this year the grades for them have fallen again.

WBOC reports that of the six areas there were four scores of F one D-Plus and one D.

Excess amounts of Nitrogen can cause algae blooms which eliminates the oxygen in the water.

Chesapeake Bay Foundation

BALTIMORE (AP) - Officials say there is a smaller than normal "dead zone" in the Chesapeake Bay, as well as clearer water, more bay grasses and an increase in the crab population.

According to a joint forecast from the National Oceanic and Atmospheric Administration and the U.S. Geological Survey, the bay's low-oxygen dead zone is expected to be 1.58 cubic miles this year. That's about 10 percent less than the long-term average of 1.8 cubic miles dating from 1985.

There’s a new study that finds harmful algae blooms in the Chesapeake Bay and its tributaries have been increasing dramatically over the last 20 years.

This is in addition to the seasonal algae blooms that occur when the weather warms up in the spring and the summer.

One strain Prorocentrum minimum was found to have doubled during the period running from 1991 through 2008 while another cyanobacteria in the tidal waters rose from 13 percent per year 23 percent during the 1990’s.
