A Sea Star Epidemic Meets Its Match

In 1969, ecologist Robert Paine coined the term ‰ÛÏkeystone species,‰Û 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 algae, kelp, urchins, mussels, and various species of fish, causing him to theorize the importance [‰Û_]

Demonstration Projects Aim to Measure Marine Biodiversity

Squib: 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.

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.
