News Journal: Wetland loss the issue in Delaware Bay

Jonathan Sharp, a professor emeritus at the University of Delaware, studied the chemistry of Delaware River and Bay for more than 30 years, watching from a front-row seat as water quality began to improve with the passage of the Clean Water Act. And while there have been many environmental changes in the estuary, a long-term shift in temperature is not one of them.

“There’s so much variability,” he said.

But water temperature isn’t the only factor that influences fish populations.

As temperatures warm around the globe, as is projected, sea level is expected to continue to rise.

And that, along with shifts in salinity, could have enormous implications for the Delaware Estuary, said Danielle Kreeger, director of science for the Partnership for the Delaware Estuary.
