Valuable Creeks and Shoals

In spite of the very spotty horseshoe crab spawn, the shorebirds on Delaware Bay seem to be gaining weight on schedule.  Below you will find a graph composed of the average weights of all the red knots by our team for the last 20 years. The curve is the result of combining all the data we collected and shows the sweet spot for most knots. As they arrive they take time to gain weight but after about 5 days they start gaining weight rapidly.  After the 26th or so, birds start reaching the critical weights necessary to safely reach the…

Sand and Spring on the Delaware Bayshore

The movement of sand on the Delaware Bay remains a mystery to coastal geologists. Unlike the Atlantic coast, where currents create a longshore drift which pushes sand generally southward, Delaware bay sand moves at the whim of both bay and creek currents and prevailing winds. The sand on any beach can move differently than adjacent beaches and sometimes in different directions on the same beach. This is what Steve Hafner of Stockton University suspects will happen with the sand at Fortescue. A small point made by the bending road, divides the beach and may determine if sand moves to the north towards the…

Beaches Are Growing And Reefs Are Being Built

The two beaches slowly take form but already promise better breeding habitat for horseshoe crabs. H4 adds about 2000 tons of Ricci Bros Sand every day, slowly building towards our goal of 48,000 tons on Fortescue Beach. We are now at 20,500 tons. One can now envisage the final beach and the sheer volume of sand it will take to make it. Boomer Huen running the front end loader and bulldozer pushes sand into the inter-tidal zone and the night time high tide reshapes it. Its not a loss however, the sand moves into the designed beach profile that Steve…

Constructing Fortescue and Thompson’s Beach in 2015

The construction teams in Fortescue and Thompson’s are now moving as fast as possible to finish the restoration work before the arrival of the horseshoe crabs in Delaware Bay. Each company follows a different procedure for building Fortescue and Thompson’s beaches. At Fortescue, the town rebuilt an existing berm of rubble that protected the beach road after Hurricane Sandy destroyed ​the berm​. They then capped it with unformed concrete. H4’s excavator moves slowly down the reformed berm to load sand on the inter​-​tidal beach to create an out-of-tide roadway for the bulldozer (see video above). Subsequent sand is used to…
