That information, paired
with aerial surveys currently mapping the ice shelf and the sea floor beneath it, will help scientists assess the stability of the Ross Ice Shelf as they seek to understand how quickly Antarctica will lose ice in a warming world and what that will mean for sea level rise globally.

completed aerial survey of the Great Barrier Reef has confirmed that a coral bleaching event is taking place for the second consecutive year (Credit: Ed Roberts)

for aerial surveys and borehole samples — revealing the 24 most promising mineral deposits.
SPECTRUM NEWS VIDEO: Continuing from our last installment of Going Green, an
extensive aerial survey of the Adirondack Park pegs the number of moose at about 400 — but helicopter tracking of moose is just one of several research projects underway.
DEC Commissioner Basil Seggos says early indications from
aerial surveys show that around 73 percent of bald eagle territories are occupied this year.
The cub production in Hudson Bay is only about 20 - 40 % of historic levels from the 1980s - 90s (this is based on the
recent aerial survey results from Hudson Bay that was covered some in the media recently).
A similar NASA -
led aerial survey is headed to Puerto Rico this week to assess lingering damage to rainforests and coastal wetlands nearly seven months after Hurricane Maria.
«But our study found that eDNA surveys improved the detection of manatees in the wild, compared to the more traditional
aerial survey methods.
A recent
aerial survey revealed thousands of ancient Maya structures previously hidden beneath the dense Guatemalan jungle, including houses, irrigation canals, fortifications, and even a pyramid.
The 2015 - 16
aerial survey covered the areas of Boma, Badingilo, Nimule, Southern, and Shambe National Parks, and the proposed Loelle protected area.
They report in the journal Science that a succession of
aerial surveys combined with multiple satellite observations has established that the base of the glacier is being eroded rapidly by a mix of warmer ocean water and increasing amounts of meltwater from the surface of the Greenland ice sheet.
Using
aerial survey photographs, the authors of this study assessed the presence, number, and total area of gull - inflicted lesions on 2680 living mother - calf pairs in 1974 - 2011 and ~ 200 stranding photographs of dead calves in 2003 - 2011 around Península Valdés, Argentina.
To determine how much ice and snowfall enters a specific ice shelf and how much makes it to an iceberg, where it may split off, the research team used a regional climate model for snow accumulation and combined the results with ice velocity data from satellites, ice shelf thickness measurements from NASA's Operation IceBridge — a
continuing aerial survey of Earth's poles — and a new map of Antarctica's bedrock.
The U.S. Department of Agriculture (USDA) announced today that the U.S. Forest Service has identified an additional 36 million dead trees across California since its
last aerial survey in May 2016.
The researchers combined a regional snow accumulation model and a new map of Antarctica's bedrock with ice shelf thickness, elevation and velocity data captured by Operation IceBridge — an ongoing
NASA aerial survey of Greenland and the South Pole.
* This item has been amended to confirm that DOE -
sponsored aerial surveys began measuring radiation around the plant about 1 week after the reactor was hit by a tsunami, not 10 days.
Six days after its initial discovery, AWI scientists conducted a more
detailed aerial survey of the circular feature in the ice shelf, taking photos and videos, and collecting laser altimeter and radar data mapping the feature's contours in detail.
Bleaching was more severe in 2002,
when aerial surveys showed that over 50 % of reefs experienced some coral bleaching.
The installation will be based on MacCallum's own architectural photographs of the plant taken in 1986, and will also include archival photographs,
aerial survey photos, images from the company's promotional material and film -LSB-...]
NYSERDA Completes First Phases of World's Largest - Ever
Digital Aerial Survey of Offshore Wildlife Along Long Island Coast
Terry Hughes, director of the ARC Center of Excellence for Coral Reef Studies at James Cook University in Townsville, Australia, is one of a team
making aerial surveys of the reef to assess the extent of the bleaching.
Scientists labeled 2016 the worst bleaching event in the Reef's history
after aerial surveys revealed severe damage throughout the northern and middle sections, with only the southern, cooler third left unharmed.
They tested the model against regional forest mortality observations from scientific forest plots,
aerial surveys done by the U.S. Forest Service, and satellite measurements.
But there's nothing conventional about exploration in the Arctic; scarce daylight for much of the year, a hostile climate and ocean variously covered by solid sea ice and amorphous, moving ice floes, all make surface navigation and
even aerial surveying dangerous, inefficient and vastly expensive.
That precision is unlike any other option on the market for leak detection, such
as aerial surveys, human patrols or satellite imaging, which are unreliable at catching small leaks.

A severe coral bleaching event spurred by high ocean temperatures has struck the Great Barrier Reef for an unprecedented second time in 12 months, reveal
aerial surveys released April 10 by scientists at James Cook University in Townsville, Australia.
Conservation groups can also pay police to
perform aerial surveys of areas vulnerable to logging, but they are too expensive to do frequently.
Scientists have used
old aerial surveys to chart surface changes in the Arctic and Antarctic, for example by studying photographs of Greenland's glaciers to document their history.
«For more than 30 years we have carried out an
annual aerial survey of waterbirds in an area covering almost a third of the continent.
For this study, the researchers used photos from a
systematic aerial survey of Greenland's glaciers conducted from 1978 to 1987.
These amounts, measured and recorded by video underwater, match very closely with the
broader aerial surveys of more than 750 reefs also being conducted by the National Coral Bleaching Taskforce.
For the second time in just 12 months, scientists have recorded severe coral bleaching across huge tracts of the Great Barrier Reef after completing
aerial surveys along its entire length.
