Scientists seek to learn why a parovirus present in sea stars since 1942 has become so virulent in recent years. In 1969, ecologist Robert Paine coined the term “keystone species,” in reference to the sea star species Pisaster ochraceus. His experiments, which involved removing coastal sea stars from the ecosystem, caused die-offs, overgrowth, or emigration in surrounding species such as … Read More
Demonstration Projects Aim to Measure Marine Biodiversity
U.S. agencies have launched a pilot project to establish a marine biodiversity observation network. The program, to measure marine biodiversity and integrate data across organizations, faces huge challenges but even greater rewards
The Global High Frequency Radar Network
By Dr. Hugh Roarty Research Project Manager Coastal Ocean Observation Laboratory Rutgers University Co-authors: Ms. Lisa Hazard, Dr. Lucy Wyatt, Dr. Jack Harlan and Mr. Enrique Alvarez Fanjul The Global High Frequency Radar Network is a vision for a global operational system measuring ocean surface currents to support monitoring of marine and coastal ecosystems. The measurement of ocean currents is … Read More
NASA’s CYGNSS Constellation of Hurricane Remote Sensing Satellites
A new NASA satellite mission, CYGNSS (Cyclone Global Navigation Satellite System), combines the all-weather performance of GNSS bistatic ocean surface scatterometry with the sampling properties of a constellation of satellites. This will result in spatial and temporal sampling properties which are markedly different from conventional imagers.
Students Build Their Resume While Building Underwater Vehicles
Hands-on learning while building underwater remotely operated vehicles (ROVs) helps young students connect with marine habitats, and gets them excited about science, math and engineering.
Call for Papers — Oceans Environment and Technologies
Earthzine (earthzine.org) was established in 2007 as an outreach activity for the GEO (Group on Earth Observations) and GEOSS (Global Earth Observation System of Systems) initiative. As a newly adopted publication of the Oceanic Engineering Society, we seek contributions to bolster Earthzine’s coverage of oceans-related activities.
