The AIM (Aerial Imaging and Mapping group) collected UAS imagery for scientists at The Marine Biological Laboratory (MBL) from the Plum Island estuary in Rowley MA.  Inke Forbrich from MBL will lead the analysis looking at the reflectance index NDVI for vegetation surrounding a gas flux tower installed in t

Rivers in the western U.S. rivers are experiencing changes in nutrient loading because of rapid urban development, but the effects of changing nutrient loading on the structure and function of stream ecosystems, especially fish habitat, are not fully understood.

A California myotis (Myotis californicus) gets ready to fly away after identification and measurements are taken. USGS is conducting research in collaboration with NPS to learn about the roosting ecology of Western bats in an effort to improve management and conservation of bat populations.

Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae (the deer family; referred to as “cervids”). Affected animals include deer, elk, moose, and reindeer.

USGS scientists deploy a monitoring buoy on Lake Hopatcong, New Jersey, to monitor water-quality conditions and a harmful algal bloom in near real-time. USGS scientist Karl Braun is photographed.

USGS scientists Lisa Carper and Jon Cohl deploy a monitoring buoy at Lake Hopatcong, New Jersey, to monitor water-quality conditions and a harmful algal bloom in near real-time.

The New Jersey Department of Environmental Protection advised the public to avoid swimming in or contact with Lake Hopatcong water due to a harmful algal bloom confirmed in June 2019 by aerial surveillance. To help study water-quality conditions and the bloom’s severity, the USGS installed a monitoring buoy on the lake in July.

Two portable sensors: a strong motion sensor (to record strong shaking that can be felt) and a broadband sensor (to record weak motion for detecting small earthquakes) buried into the ground to detect earthquakes. These stations can be quickly deployed and send real-time data back to the USGS via cellular telemetry immediately after they are installed.

Kate Scharer (USGS) provides CO CAPT Paul Dale (Navy) with the field mapping team’s initial product, showing the surface fault rupture at NAWSCL as well as the temporarily deployed seismic and GPS sensors that were rapidly deployed. Contributions of field data from within the base were from CGS & USGS, and from outside the base were from Univ.
