Sea levels in coastal areas can be affected by a number of factors: tides, winds, waves, and even barometric pressure all play a role in the ebb and flow of the ocean. For the first time, however, a new study led by the Woods Hole Oceanographic Institution (WHOI) has shown that river outflow could play a role in sea level change as well.

Scientists have detailed how they designed and tested a biodegradable ocean drifter that tracks and measures shallow-depth (0.60 meter) surface currents. Drifters are an important tool that allows researchers to capture data of ocean currents over long periods of time. However, the study authors note that “because of the large numbers involved, drifters must be low-cost, compact, easy to handle, and also made of materials harmless to the environment”.

For the second time in three years, Florida Gov. Rick Scott has issued a state of emergency in Lee and Martin counties, due to massive freshwater cyanobacteria blooms that have turned Lake Okeechobee and the Caloosahatchee and St. Lucie rivers into public health hazards.

With fish and other marine life becoming increasingly important for feeding our growing human population, science-based fisheries management is crucial to keep stocks sustainable. How can acoustic-based scientific instruments contribute in this respect, while also opening up opportunities for interdisciplinary scientific research?
