Hydrographer Jonathan Cohl sprays down the boat and trailer, used to deploy a Harmful Algal Bloom (HAB) water quality monitoring buoy on Lake Hopatcong, with a decontamination solution. This is a very important step between missions when vessels are used in multiple bodies of water.

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.

California Geological Survey and USGS geologists and geophysicists with National Guard and Navy personnel view road damage from 3 to 5 feet of right-lateral motion near the expected maximum slip locality along the primary tectonic rupture associated with the M 7.1 event.

Fault rupture crosses dirt road, with California Geologial Survey vehicles for scale. Displacement at this location is primarily normal (vertical). Photograph taken near the northern end of the rupture resulting from the M7.1 Searles Valley earthquake.
