Mapping Global Sea-Level Variations with Sentinel-3A

Presented this week at ESA’s Living Planet Symposium in the Czech Republic, this new map shows a month of ‘sea-level anomaly’ measurements from Sentinel-3A. The satellite has only been in orbit since 16 February 2016 and is therefore still being commissioned for service. Nevertheless, measurements made by its radar altimeter between 3 March and 2

Online Tool Maps Louisiana’s Water Flow Interactions to Preserve State’s Fresh Water

BATON ROUGE, La.—As part of an effort to preserve Louisiana’s fresh water resources, RTI International worked with The Nature Conservancy (TNC) to develop two online tools, released today, that offer a first-of-their-kind look at how Louisiana’s waters interact with each other. These tools will help fishermen, oystermen, planners, decision makers, and all Louisianans understand the

Researchers Find Earth May Be Home to 1 Trillion Species

BLOOMINGTON, Ind.—Earth could contain nearly 1 trillion species, with only one-thousandth of 1 percent now identified, according to a study from biologists at Indiana University. The estimate, based on the intersection of large datasets and universal scaling laws, appears today in the Proceedings of the National Academy of Sciences. The study’s authors are Jay T.

Model Predicts How Forests Will Respond to Climate Change

VANCOUVER, Wash.—Drought could render the U.S. Northeast’s mixed forests unsustainable after 2050 while Washington’s Cascade Mountains may require tropical and subtropical forest species, according to researchers using a new type of mathematical model at Washington State University. The Tolerance Distribution Model (TDM) is the first to use the tolerances of different types of forests to

New Field of Computational Sustainability Emerges

An interdisciplinary team of programmers, theorists, applied mathematicians, economists, biologists and environmental scientists have helped create a new field, computational sustainability, addressing challenges that computer scientists have not traditionally handled. Together, they tackle a range of issues from wildlife management to poverty reduction.

Ocean Currents Push Phytoplankton—and Pollution—Around the Globe Faster Than Thought

The billions of single-celled marine organisms known as phytoplankton can drift from one region of the world’s oceans to almost any other place on the globe in less than a decade, Princeton University researchers have found. Unfortunately, the same principle can apply to plastic debris, radioactive particles and virtually any other man-made flotsam and jetsam

Royal Navy Uses Pilotless Aircraft to Navigate Through Ice

A tiny pilotless aircraft, built by the University of Southampton, has launched from the Royal Navy’s ice patrol ship HMS Protector for the first time to assist with navigating through the Antarctic. The 3D-printed aircraft, along with a quadcopter, scouted the way for the survey ship so she could find her way through the thick

Clear-Cutting Destabilizes Carbon in Forest Soils, Dartmouth Study Finds

Clear-cutting loosens up carbon stored in forest soils, increasing the chances it will return to the atmosphere as carbon dioxide and contribute to climate change, a Dartmouth College study shows.

Climate Science Project Aims to Understand Amazon Impacts

Further understanding the links and interactions between the Brazilian Amazon rainforest and the world’s climate is the focus of a major new research programme, funded by the Newton Fund The three-year £4-million program, known as Climate Science for Service Partnership (CSSP) Brazil, will bring together scientific researchers and organisations from the UK and Brazil, in

Cold Mountain Streams Offer Climate Refuge

A new study offers hope for cold-water species in the face of climate change. The study, published today in the Proceedings of the National Academy of Sciences, addresses a longstanding paradox between predictions of widespread extinctions of cold-water species and a general lack of evidence for those extinctions despite decades of recent climate change. The
