Using Plant Physiologic Responses to Environmental Conditions to Improve Species and Habitat Management in Hawaii
Recent studies show that past and ongoing environmental changes have been substantial and have likely already affected conservation efforts in Hawai‘i. Much of the state has experienced substantial drying, including decreases in mean annual precipitation since the 1920s, longer rainless periods, and decreasing stream flow. Temperatures have been increasing in Hawai‘i for the last 40 years,...

Hawaiʻi Rainfall--current conditions
Continuously recording rainfall sites utilize equipment that automatically record and store the amount of rainfall at specific intervals. Many sites are equipped with telemetry so that information can be electronically transmitted and displayed on the internet in real time.
Hawaiʻi Water Quality--current conditions
Suspended-sediment concentrations are determined from samples collected by an autosampler or collected manually.
Hawaiʻi Groundwater--current conditions
At some sites, groundwater levels in wells are manually measured, using steel or electrical tapes or pressure transducers. Other sites utilize electronic equipment to record and store the water levels at specific intervals. Some sites are equipped with telemetry so that information can be electronically transmitted and displayed in real-time on the internet.
Hawaiʻi Streamflow--current conditions
Continuously recording surface-water stations are stations with equipment that automatically record and store data at specific intervals. Many stations are equipped with telemetry so that information can be electronically transmitted and displayed on the internet in real time.
USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
The 3DEP products and services available through The National Map consist of standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.

The Defense Minerals Administration (DMA), Defense Minerals Exploration Administration (DMEA), and Office of Minerals Exploration (OME) mineral exploration programs were active over the period 1950–1974. Under these programs, the Federal Government contributed financial assistance in the exploration for certain strategic and critical minerals. The...Frank, David G.
Dim ultraviolet light as a means of deterring activity by the Hawaiian hoary bat Lasiurus cinereus semotus
Widespread bat fatalities at industrial wind turbines are a conservation issue with the potential to inhibit efficient use of an abundant source of energy. Bat fatalities can be reduced by altering turbine operations, but such curtailment decreases turbine efficiency. If additional ways of reducing bat fatalities at wind turbines were available...Gorresen, P.

Avian malaria in Hawaiian forest birds: Infection and population impacts across species and elevations
Wildlife diseases can present significant threats to ecological systems and biological diversity, as well as domestic animal and human health. However, determining the dynamics of wildlife diseases and understanding the impact on host populations is a significant challenge. In Hawai‘i, there is ample circumstantial evidence that introduced...Samuel, Michael D.; Woodworth, Bethany L.; Atkinson, Carter T.; Hart, P. J.; LaPointe, Dennis
One carp, two carp: are there more carp in the Wailoa River?
The February, 2015 issue of Hawaii Fishing News included the annual list of Hawai`i records for the largest fish of various species caught in the state. Among the new records was one for a 15-pound grass carp (Ctenopharyngodon idella) caught by Avery Berido in the Wailoa River at Hilo on September 13, 2013. A photograph taken by Mr. Berido of the...Mundy, Bruce C; Nico, Leo; Tagawa, Annette
From ridge to reef—linking erosion and changing watersheds to impacts on the coral reef ecosystems of Hawai‘i and the Pacific Ocean
Coral reef ecosystems are threatened by unprecedented watershed changes in the United States and worldwide. These ecosystems sustain fishing and tourism industries essential to the economic survival of many communities. Sediment, nutrients, and pollutants from watersheds are increasingly transported to coastal waters, where these contaminants...Stock, Jonathan D.; Cochran, Susan A.; Field, Michael E.; Jacobi, James D.; Tribble, Gordon

The Pedestrian Evacuation Analyst is an ArcGIS extension that estimates how long it would take for someone to travel on foot out of a hazardous area that was threatened by a sudden event such as a tsunami, flash flood, or volcanic lahar. It takes into account the elevation changes and the different types of landcover that a person would encounter along the way.
Fissure 6 (photo center) showed signs of activity overnight, producing small amounts of spatter and feeding short lava flows. Fissure 6 is located about 2.2 km (1.4 mi) downrift from Fissure 8.
USGS Hawaiian Volcano Observatory, Status of Kīlauea Volcano, 10:00 a.m. HST, June 18, 2018, Liz Westby - USGS Geologist
Lava enters the ocean entry in the vicinity of Vacationland, producing a vigorous laze plume. Lava flowing into the ocean has built a delta of flows, rock rubble and black sand, which is over 320 acres in size.
Inward slumping of the rim and walls of Halema‘uma‘u continues in response to ongoing subsidence at the summit. Sulfur dioxide emissions from the volcano's summit have dropped to levels that are about half those measured prior to the onset of the current episode of eruptive activity. This gas and very minor amounts of ...
Occasionally, minor amounts of lava briefly spill over the lava channel levees. The spill overs are the shiny gray lobes along the channel margins. The lava flow field has been relatively stable with little change to its size and shape over the past few days. View to the east, with the ...
At Kīlauea Volcano's summit, inward slumping of the rim and walls of Halema‘uma‘u continues in response to ongoing subsidence. In this view to the southwest taken after this morning's event, a section of dark-colored wall rock (center left) has detached and dropped downward into the crater.
Caly isn't likely to wonder off off, but with a remote camera and monitoring station online 24-hours a day, USGS and partners at the State of Hawai‘i Division of Forestry and Wildlife, University of Hawai‘i, and the USFWS can learn how an extremely rare plant is responding to changes in environmental conditions.
With ash eruptions occurring from Kilauea’s summit this week, there is a threat of an even larger steam-driven violent explosion. Such an eruption could happen suddenly and send volcanic ash 20,000 feet into the air, threatening communities for miles.
Representatives of the news media are invited to join a telephone briefing for the latest updates on Kīlauea's volcanic activity and its impacts.
Honolulu, Hawaii – Control efforts such as the removal of shipwrecks and application of chlorine may help mitigate the damaging effects of corallimorph, which is a type of invasive anemone, on valuable coral reefs in the Central Pacific Ocean, according to a new U.S. Geological Survey study.
Coral reefs already stressed by ocean acidification are particularly vulnerable to polluted groundwater, according to a recent study by USGS geologist Nancy Prouty and colleagues.

Sudden flooding hit islands of global importance for Pacific birds highlighting threats and opportunities for conservation planning
Just like smog and fog, this EarthWord is not what you want to see while driving...
In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai’i, U.S. Geological Survey researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.
