The Colors of NJ Salt Marshes

The tidal salt marshes of Southern New Jersey have taken on a greenish-gray coloration the last few weeks due in part to the flooding from the recent coastal storm this past March. Hans Toft, a retired Marine Sciences teacher at Cape May Technical High School, explained the odd color is caused from silt and diatoms from algae blooms being deposited during the flood tides and clinging to the brown marsh grass. The silt and diatoms are rich in nutrients and act as a fertilizer enriching the growth of new marsh grasses which are just beginning to bloom. Tuesday April 10, 2018.
