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.

Panama saves whales, protects world trade

Originally Published by Science Daily – A new scheme to separate boat traffic coming into the Panama Canal from humpback whales migrating through tropical waters, based on two research papers, has been approved by the International Maritime Organization. Panama is a leader in global commerce and a steward of exceptional marine biodiversity. Nearly 17,000 commercial vessels cross the Gulf of Panama each year. This number is expected to increase significantly when new locks now under construction permit larger, “post Panamax” vessels to transit the Canal and enter its ports.

The latest developments in Google Ocean

Originally Published by Google Earth – Google first released their 3D Ocean feature in Google Earth more than five years ago, and it’s something that has seen steady improvements over the years. Here are some of the more interesting recent developments.

Twenty Buses a Day: The High Stakes Race to Create a Global Cholera Early Warning System

What infectious disease kills the most children under the age of five? If you guessed malaria or AIDS, guess again. Cholera claims more victims than either of those diseases. Now, a team of researchers are developing a method to provide early warning of cholera outbreaks. If successful, the effort could drastically reduce the number of cholera deaths.

OGC netCDF: Powerful Tool for Science

A widely used “fluid earth systems” data model and data access standard called netCDF now provides an important bridge between GIS and the complex 4-D processing systems used in oceanography and atmospheric sciences. By bringing netCDF into the Open Geospatial Consortium (OGC) standards organization, the netCDF community has given climate scientists, for example, a streamlined method for bringing virtually all types of spatial/temporal data and processing into climate science models and workflows.

Global Sea Level Rise Dampened by Australia Floods

Global Sea Level Rise Dampened by Australia Floods Originally published by ScienceDaily – When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by the National Center for Atmospheric Research (NCAR) shows that when three atmospheric patterns came together over the Indian and Pacific oceans, they drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably. Unlike other continents, the soils and topography of Australia prevent almost all of its precipitation from running off into the ocean.

Timing a Rise in Sea Level

Timing a Rise in Sea Level Originally published by The New York Times – Thirty-five years ago, a scientist named John H. Mercer issued a warning. By then it was already becoming clear that human emissions would warm the earth, and Dr. Mercer had begun thinking deeply about the consequences.
