Continuous stream discharge, salinity, and associated data collected in the lower St. Johns River and its tributaries, Florida, 2021

The U.S. Army Corps of Engineers, Jacksonville District, is deepening the St. Johns River channel in Jacksonville, Florida, by 7 feet along 13 miles of the river channel beginning at the mouth of the river at the Atlantic Ocean, in order to accommodate larger, fully loaded cargo vessels. The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, monitored stage, discharge, a

Technical note—Performance evaluation of the PhytoFind, an in-place phytoplankton classification tool

In 2019, the U.S. Geological Survey evaluated the performance of the Turner Designs, Inc. PhytoFind, an in-place phytoplankton classification tool. The sensor was tested with sample blanks, monoculture and mixed phytoplankton cultures, and turbidity challenges in a laboratory, and was tested on a 120-mile survey of the Caloosahatchee and St. Lucie Rivers in Florida, including Lake Okeechobee. Resu

New larger benthic foraminifera from the subsurface Lower to Middle Eocene Oldsmar Formation of southeastern Florida (USA)

We describe two larger benthic foraminiferal taxa collected from wells drilled in the subsurface Eocene rocks of southeastern Florida that are new to peninsular Florida and the Caribbean region. Saudia floridana n.sp. is characteristic of a foraminiferal assemblage, along with Helicostegina gyralis, wide forms of the Cushmania americana group, and Gunteria floridana, in an upper part of the Oldsma

Lake Okeechobee Sediment Transport Project

Suspended sediment from Lake Okeechobee might be a source of nutrients that helps trigger the growth and development of harmful algal blooms in the Caloosahatchee and St. Lucie Rivers.

Everglades Depth Estimation Network (EDEN)

In the early 2000s, USGS developed the Everglades Depth Estimation Network (EDEN) to provide water-level data for scientists, decision-makers, and managers to help monitor and assess Everglades restoration. EDEN is a real-time integrated network of 275 water-level gages, water-surface models, and applications that provides 400 x 400 meter gridded daily water-level data across the freshwater part...

Potentiometric Surface of the Upper Floridan Aquifer in the St. Johns River Water Management District and Vicinity, Florida

Due to reduced funding, the May 2009 map will be the last publication of the Potentiometric Surface of the Upper Floridan Aquifer in the St. Johns River Water Management District and Vicinity, Florida unless additional funding sources are identified. Water-level elevations will still be measured semi-annually and published in the Annual Data Report as long as funding is available. The Scientific...
