Successful ocean-monitoring satellite mission ends

The Jason-2/Ocean Surface Topography Mission (OSTM), the third in a U.S.-European series of satellite missions designed to measure sea surface height, successfully ended its science mission on Oct. 1. NASA and its mission ...

Sea level rise requires extra management to maintain salt marshes

Salt marshes are important habitats for fish and birds and protect coasts under sea level rise against stronger wave attacks. However, salt marshes themselves are much more vulnerable to these global change threats than previously ...

Q&A: Designing a better local tsunami warning system

On a Friday afternoon in the spring of 2011, the Tōhoku-Oki earthquake shook northeastern Japan for six minutes and shifted the country's main island by 8 feet. Minutes later, residents began receiving tsunami warnings through ...

It's not so easy to gain the true measure of things

I teach measurement – the quantification of things. Some people think this is the most objective of the sciences; just numbers and observations, or what many people call objective facts.

More glaciers in East Antarctica are waking up

East Antarctica has the potential to reshape coastlines around the world through sea level rise, but scientists have long considered it more stable than its neighbor, West Antarctica. Now, new detailed NASA maps of ice velocity ...

New tool to predict which plants will become invasive

Around the world, over 13,000 plant species have embedded themselves in new environments—some of them integrate with the native plants, but others spread aggressively. Understanding why some plants become invasive, while ...

A growing climate niche for giant trees

New techniques using lasers on satellites reveal where giant trees are. An international group of scientists led by Wageningen University & Research and Nanjing University, now showed that across climate zones 'giant forests' ...

3-D crop imaging helps agriculture estimate plant height

Building three-dimensional point clouds from high-resolution photos taken from unmanned aerial vehicles or drones may soon help plant breeders and agronomists save time and money compared with measuring crops manually.

Accounting for tree height, biodiversity is 3-D

The species-area relationship (SAC) is a long-term pattern in ecology and is discussed in most academic Ecology books. Its implications are relevant for many ecological, evolutionary, conservation and biogeographic purposes. ...
