An Ocean of Career Opportunities

Ocean

Did you know that 20 percent of our economy is based on ocean-related activities?

There are well-known sea-faring ventures — fisheries and aquaculture, transportation, and recreation and tourism. But there are plenty of less obvious areas that also rely on the ocean, everything from energy and exploration activities, to national security and defense, to telecommunications, search and recovery operations and scientific and medical research.

If you’re curious to explore this sea of opportunities, check out www.OceanCareers.com. According to Deidre Sullivan, OceanCareers.com Project Director at the Marine Advanced Technology Education (MATE) Center at Monterey Peninsula College in Monterey, California, it’s a one-stop web site for anyone who’s interested in learning more about ocean occupations.

“When we first created the web site, in 2004, there was almost nothing out there for [students and job-hunters] in terms of ocean-career resources,” Deidre tells us. “OceanCareers provides four comprehensive databases with hundreds upon hundreds of resources.”

Whether your primary interest is to find a job or internship, or to understand what type of educational programs are available in marine science and technology, you’ll find it here. The first database provides detailed information on the more than 300 educational institutions around the country that offer ocean-related academic programs; the second offers descriptions of more than 50 ocean occupations, including overviews of the positions’ tasks and duties, the salary ranges and workforce trends; the third is a full overview of educational competencies needed in 24 different disciplines to be able to get a job; and the fourth provides users with links to more than 200 ocean-related professional societies.

“Students from all over the country use OceanCareers,” (www.OceanCareers.com) says Deidre. “We’ve found that people really go through a lot of the information on the site. It’s easy to navigate, you can get anywhere in the site with just two clicks. It’s been rewarding to have people tell me that it’s the most important tool they’ve used [in their search for career information].”

What are users most often looking for in their searches? “Not surprisingly, people want to know much education they need for a particular career and how much salary they can earn in a particular field,” she says, adding that all content is frequently updated and kept current. (The MATE team has also put together a print version of the site’s educational content, “The Guide to Marine Science and Technology Programs in Higher Education.” You can download it at https://www.mtsociety.org/publications/higherguide.aspx, or can order a copy for $5.)

Exploring the Depth of the Ocean

ROV Jason

ROV Jason

In this week’s episode, ATETV was at the MATE ROV competition in San Diego, where we heard from students who were busy designing and crafting remotely operated vehicles. This led us to wonder, just what is an ROV made of and what are these underwater robots used for?

Remotely operated vehicles can plumb 3,000 to 12,000 feet below the ocean – depths that would be far too difficult and dangerous for human divers to access — and were initially developed by the U.S. Navy in the early 1960s for use in deep-sea rescue operations and recovery of objects from the ocean floor. Ranging in size from the proverbial breadbox to a full-size minivan, the unmanned devices are typically constructed of aluminum and titanium and painted in high-visibility yellow. They are outfitted with a special substance to ensure buoyancy.

The ROVs are tethered to ships, enabling a human controller to be located above water where a series of communications cables, and energy sources are housed. At a minimum, the robotics contain a camera or other visual device that enables them to “see” underwater, but many of today’s ROVs are also outfitted with a wide variety of sophisticated tools. Today’s robots are also generally equipped with hydraulic “arms” that enable the human operators to work long-distance, similar to the way surgeons use laparoscopic instruments when performing minimally invasive surgery.

In recent weeks, ROVs have been in news reports on the oil spill cleanup in the Gulf of Mexico, where the underwater robots are playing key roles. In fact, ROVs have been a staple of the oil industry since the mid-1970s, when they began replacing human divers and manned submersibles for drilling support and subsea construction services to enable deepwater exploration and development projects throughout the world.

But as it turns out, ROVs have lots of different functions – and lots of jazzy names. “Jason,” for example, is a scientific ROV developed at the Woods Hole Oceanographic Institute in Falmouth, Massachusetts, named after the mythical Greek adventurer and ocean explorer and used for studying the depths of the ocean floor. And on the opposite coast, in Monterey, California, the Nature Conservancy is using an ROV dubbed “The Beagle” for a five-year study to assess the impact of trawl fishing in soft-bottom seafloor habitats. (The Beagle was named in honor of Charles Darwin’s 200th birthday and the famous research ship he sailed to the Galapagos Islands.) Check out the Nature Conservancy website to watch videos about how ROVs work and glimpse the ocean depths through the “eyes” of these underwater robots

ROVs have also been used to locate historic shipwrecks, including the Titanic; to perform mine clearing and other harrowing military tasks; and to enable salvage operations for downed planes or sunken boats, serving as “birddogs” to assess potentially dangerous conditions before scuba divers are sent in.

Gee, in answer to our original question, it seems like ROVs do pretty much everything!
