On a six-week business trip this winter, Cassandra Lopez posted updates to her friends on Facebook, and conversed with her family on Gmail chat. What made these interactions unique was that Cassandra was on-location in the Southern Ocean, writing oceanography articles from one of the world's most remote places. She was aboard the R/V Roger Revelle, a vessel of the Scripps Institution of Oceanography (SIO) in La Jolla, CA, which, like most large ships of its generation, comes with advanced communication systems, as well as crew members devoted to technical support. The HiSeasNet satellite system on the R/V Roger Revelle enables it to better serve as a laboratory for scientific research by providing constant internet access. It also has the byproduct of helping seagoing researchers and crew members maintain relationships back home.

On top of a fairly consistent email service, several crew members maintain blogs to tell friends and family about their shipboard experiences. Joe Ferris, a Second Mate, recently posted on travel plans, piracy evasion, foul weather navigation, and working out. Resident Technician Dave Langner takes advantage of the Realtime camera system, which uploads images from the ship to a San Diego database every ten minutes, to keep in touch with his mother. "Sometimes I'll email her just before I go on deck," he says, "and she can see me working from her computer screen."

Veterans of ship life say that communication has improved dramatically in the past two decades. Acoustics specialist Jules Hummon recalls that when she first started going to sea in 1988, images were faxed via satellite-linked modems, and it took half an hour to transmit a page-long image of sea surface temperatures. On her first trip, she was billed by the kilobyte for two personal faxes: a letter from her mother, and a Calvin and Hobbes comic strip from her husband. They cost her over $100 to receive. These days, she can download reasonably-sized images through email using the HiSeasNet satellite connection at no additional cost.

Still, the ability to stay connected to land is a mixed blessing for oceanographers, who appreciate the relative simplicity of life at sea. In a survey taken of scientists and crew members on the R/V Revelle's CLIVAR I8S expedition in March, most respondents echoed the sentiment of Chief Scientist Jim Swift, who listed "getting away from the distractions of professional life" as one of ship time's primary appeals. Chris Measures, a trace metals scientist and oceanography professor, finds that better communication has increased his responsibilities at sea. Besides being constantly on-call for the six weeks of CLIVAR I8S, he was in charge of coordinating a grant proposal with researchers in America, India, and Italy, which he submitted by shipboard email.

The improved capacity for communication has also brought the interruptions of personal life. Seagoers fret about termite infestations and errors in bills and pet sicknesses that they can do nothing about, barring their physical presence. Furthermore, the inconsistency of satellite connections makes it difficult to start relationships with those onshore, as the expectations of communication are hard to fulfill. On a four-week trip off the coast of Indonesia, resident technician Dave Langner thought that a budding relationship was falling apart. "It seemed like she was ignoring some important emails I had sent," he said. "It turns out she just hadn't received them." Second Mate Joe Ferris, who spends five to seven months at sea every year, doesn't bother: "I only date when I'm not working," he says.

The oceanographer tends to fall on the adventurous end of the personality spectrum, but the demands of the oceangoing lifestyle remain at odds with the standard urge to settle down. After more than a decade of traveling out of a ship's berth to exotic locales, Joe Ferris is thinking seriously about buying property and moving his things out of storage. Few give it up completely, but many cut down in their ship time as they move into the patterns of a more stable life: buying homes, finding partners, having children. Lynne Talley, a professor and researcher at the Scripps Institution of Oceanography, spent much of the ≈90's at sea, but she now devotes her time to teaching and writing on campus to stay closer to her family. Frequent emailing may not fully substitute for being at home, but it is remarkable that shipboard communications have evolved such that new oceanographers can compare sea time to business trips made by their friends in marketing and consulting. "Many careers require travel," says Cliff Buck, a graduate student at the University of Florida. "I don't really see this lifestyle as being all that unusal."
