Multi-region assessment of chemical mixture exposures and predicted cumulative effects in USA wadeable urban/agriculture-gradient streams
Chemical-contaminant mixtures are widely reported in large stream reaches in urban/agriculture-developed watersheds, but mixture compositions and aggregate biological effects are less well understood in corresponding smaller headwaters, which comprise most of stream length, riparian connectivity, and spatial biodiversity. During 2014–2017,...

Does geomorphology determine vulnerability of mangrove coasts to sea-level rise?
The greatest climate-based threat to coastlines worldwide is sea-level rise. We tested the hypothesis that tropical coasts fringed by mangroves and receiving high inputs of terrigenous sediment are less vulnerable to sea-level rise than biogenic systems dependent upon peat formation for vertical land development. An analysis of published data...

Nearshore water quality and coral health indicators along the west coast of the Island of Hawaiʻi, 2010–2014
Coral reefs worldwide are experiencing rapid degradation in response to climate and land-use change, namely effects of warming sea-surface temperatures, contaminant runoff, and overfishing. Extensive coral bleaching caused by the steady rise of sea-surface temperatures is projected to increase, but our understanding and ability to predict where...

Low-lying areas of tropical Pacific islands
Sea level is rising faster than projected in the western Pacific, so understanding how wave-driven coastal flooding will affect inhabited, low-lying islands—most notably, the familiar ring-shaped atolls—as well as the low-elevation areas of high islands in the Pacific Ocean, is critical for decision-makers in protecting infrastructure or relocating resources and people.
Pacific Island Bird Survey Design and Data Analysis
Abundance data are collected for bird populations throughout the Pacific Islands by numerous federal, state, university, and non-profit organizations. In order to ensure data are standardized and available to researchers throughout the region, interagency bird databases have been created and continue to be used. These databases contain more than a million compiled, proofed, and standardized...
Conservation Genetics of the Hawaiian Hoary Bat
The Hawaiian Hoary Bat (Lasiurus semotus) or ʻōpeʻapeʻa is the only extant land mammal native to the Hawaiian archipelago and is listed as endangered due to apparent population declines, and a lack of knowledge concerning its distribution, abundance, and habitat needs. This study is designed to apply molecular techniques to document demographic information, assess genetic variability...

The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)
The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.
The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
Thermal Imaging Camera Use: Identifying Groundwater Inputs to a Reef in American Samoa
USGS scientists used a thermal camera in American Samoa to understand the effect of land-based contaminants on an adjacent coral reef lagoon ecosystem. The infrared (IR) camera was used to capture thermal images of the lagoon to look for temperature differences to understand the distribution of freshwater entering the lagoon and the circulation of the lagoon water at various tidal levels.
Risk Analysis of Invasive Freshwater Fishes in Hawaii and Micronesia
Invasive species threaten biodiversity around the world, especially on islands. USGS scientists are helping to identify fish species that have the greatest potential to invade the fresh waters of Microneisa.

A geologists makes observations at Kilauea
Clear weather allowed HVO geologists to make observations and take measurements of the water pond at Kīlauea's summit. No major changes were observed, and the water level continues to slowly rise. Note the former HVO observation tower can be seen above the geologist's helmet.

After a sample was collected, HVO team members transferred water from the sampling device to plastic bottles. Team members took notes, measured water pH and evaluated water temperature data for each sample collected.
Water collected from the lake at the bottom of Halema‘uma‘u
Water collected from the lake at the bottom of Halema‘uma‘u is prepared for laboratory analyses at the USGS California Volcano Observatory. Results thus far reveal chemistry indicative of complex reactions among the water, magmatic gases and Kīlauea's basaltic rocks.

The scarcity or overabundance of water presents some of the most dangerous, damaging and costly threats to human life, ecosystems and property in the form of drought, floods and debris flows.
Disasters and emergencies can happen at any time, often without warning. Natural hazards threaten thousands of lives and cause billions of dollars in damage every year throughout the nation.
New Study Finds the Restoration of Forests with Active Rapid ʻŌhiʻa Death Infections May Be Possible
Hilo, Hawaiʻi – For the first time, researchers have shown that native ʻōhiʻa seedlings can survive for at least a year in areas that have active mortality from Rapid ʻŌhiʻa Death, or ROD, a fungal disease that is devastating to this dominant and culturally important tree in Hawaiian forests. This information can be useful to land managers and homeowners as they prioritize conservation actions.
On May 14, Director Reilly signed a Memorandum of Agreement with the Department of the Navy and the U.S. Fish and Wildlife Service. The MOA provides for continuity of operations for the USFWS and the USGS with construction of new office and lab facilities on the Guam National Wildlife Refuge in conjunction with DOD’s construction of a Marine Corps firing range.
U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.
This month marks the second anniversary of the largest rift zone eruption and summit collapse at Kīlauea Volcano in 200 years. In 2018, scientists at the U.S. Geological Survey Hawaii Volcano Observatory monitored more than 60 collapse events at the summit that caused the floor of Halema‘uma‘u crater to drop about 1600 feet, or more than five times the height of the Statue of Liberty.
