The Quest for Kelp and Diving with Dr. Sylvia Earle

Kelps are giant, brown algae that look a lot like plants, but actually belong to the Protist Kingdom, so they are not even closely related. However, much like trees, kelp can form vast undersea canopies, called kelp forests, teeming with marine file, feeding, breeding and finding refuge there. Kelps are cold water species that need nutrients, light and a hard seafloor to latch on to with their holdfasts (a rootlike system). This is why kelp forests are almost exclusively found in higher, colder latitudes.…

GEEC-ing out at Girls Underwater Robot Camp

By Courtney Mattison

When it comes to women’s education these days, opportunities abound—especially to get young women interested in science, technology, engineering and math (STEM). As of 2013, only about 25% of American STEM degree holders were women, but universities, nonprofits and the White House alike are working hard to change that by introducing programs and incentives aimed at inspiring girls and women to pursue careers in STEM fields. One especially exciting new organization is called Global Engineering & Exploration Counselors (GEECs). Founded by National Geographic Young Explorer and submarine pilot Erika Bergman and marine science and technology communicator and educator Samantha Wishnak, GEECs is creating opportunities for teenage girls to explore the ocean (and their interests in STEM) using underwater robots, also known as remotely operated vehicles or ROVs.…

DOER’s Sub-Ice Rover Tested in Tahoe

It almost feels like science fiction: a 28-foot long, 2,200-pound robotic submarine that can fit through a 30-inch ice borehole. But observers in Tahoe this past week can attest to the realness — and world-class engineering — of the Sub-Ice Rover (SIR) created by DOER Marine of Alameda for North Illinois University. The craft is designed to explore the ocean underneath the half mile of frozen water known as the Ross Ice Shelf in Antarctica. To clear the borehole, SIR is designed to collapse to a diameter less than 30 inches. 

Once beneath the ice, SIR expands and produces an array of high tech sensors and cameras which blast terabytes of data up the 2-mile cable to the control center. These instruments will ultimately seek to collect data about ice melt beneath the Ross Ice Shelf to better understand conditions at the interface between seawater and the base of the glacial ice, as well as investigate the sea floor and layers of sediment beneath. …
