EPA’s Floating Laboratory Lake Guardian Sails Again

After a year in lockdown due to COVID-19, the Environmental Protection Agency’s largest research vessel Lake Guardian has set sail. Eleven scientists supported by a 15-member crew will live and work aboard the ship in April 2021. The work on the Lake Guardian is EPA science at its best. Among other activities, these scientific sailors

Multiple UAV Approach Reduces Time to Survey Penguin Nests and Chicks

One of the largest Adélie penguin colonies in the world was surveyed with multiple-UAVs. Survey time was reduced from three days (with a single drone manually piloted) to less than three hours. The work was led by a team of experts from Stanford University, Point Blue Conservation Science and Conservation Metrics. UgCS software by SPH

Satellites Help South Africa Share Water Fairly

Some 20 year ago, in response to severe water shortages, the South African government passed the National Water Act, which is intended to restrict the amount of water farmers use for irrigation. However, ensuring farmers only take the water to which they’re entitled is tricky. Maurits Voogt, who works for HydroLogic, a relatively small company

Major Floods Have Increased in Temperate Climates, but Decreased Elsewhere

Severe river floods are escalating in temperate climates and putting at risk populations, livelihoods and property, according to evidence published in Geophysical Research Letters by an Oxford-led international team.  The first global examination of recent changes in the size, frequency and probability of extreme river floods using historical river records, the paper shows that dangers

Fires Raged in the Amazon Again in 2020

After intense fires in the Amazon captured global attention in 2019, fires again raged throughout the region in 2020. According to an analysis of satellite data from NASA’s Amazon dashboard, the 2020 fire season was actually more severe by some key measures. The Visible Infrared Imaging Radiometer Suite (VIIRS) sensors on the Suomi NPP and

NASA Satellites Help Quantify Forests’ Impacts on Global Carbon Budget 

Using ground, airborne and satellite data, a diverse team of international researchers—including NASA scientists—created a new method to assess how the changes in forests during the last two decades impacted carbon concentrations in the atmosphere. In addition to better understanding the overall role of forests in the global carbon cycle, the scientists were also able

Sensor Onboard SpaceX Rocket to Detect Greenhouse Gas Emissions

An optical sensor that can map methane emissions from space at a resolution 100 times higher than any other sensors was deployed on Jan. 20, 2021, with the successful launch of satellite Hugo from GHGSat. The new greater granularity will allow the identification of the source of emissions, rather than just the general area.  The

NASA’s AIM Sees First Night-Shining Clouds of Antarctic Summer

Summer in Antarctica is marked by days in which the Sun never sets, balmy temperatures that hover as high as freezing, and electric-blue clouds of ice. NASA’s Aeronomy of Ice in the Mesosphere mission (AIM) spotted the summer’s first noctilucent, or night-shining, clouds on Dec. 8, 2020. In the days that followed, the fine wisps

TRUTHS Climate Change Satellite Relies on Infrared Detector

Teledyne e2v, part of the Teledyne Imaging Group, will supply infrared detectors for the UK-led climate change Traceable Radiometry Underpinning Terrestrial and Helio Studies (TRUTHS) mission, which aims to establish an SI-traceable space-based climate and calibration observing system to improve confidence in climate-change forecasts, often referred to as a standards laboratory in space. Announced in

Noise and Light Pollution From Humans Alter Bird Reproduction

Human-produced noise and light pollution are troublesome to our avian neighbors, according to new research from a team at California Polytechnic State University, published Nov. 11, 2020 in Nature. Using NASA satellite data, the researchers got a bird’s-eye view of how noise and light negatively affected bird reproduction in North America. The team also discovered
