In the deep sea, low oxygen levels, scarce sunlight, and freezing water limit the rate at which items decompose: Something that might survive a few years on land could exist for decades underwater.

Today it is an economic and even geopolitical necessity for oil companies, in order to maintain pipelines and offshore rigs, to send divers routinely to depths of a thousand feet, and keep them at that level of compression for as long as a month at a time. The divers who do this work are almost entirely male, and tend to be between the ages of twenty-five and forty. Were they any younger, they would not have enough experience or seniority to perform such demanding tasks. Any older, and their bodies could not be trusted to withstand the trauma. The term for these extended-length descents is “saturation diving,” which refers to the fact that the diver’s tissues have absorbed the maximum amount of inert gas possible.

The BBC has produced a fabulous infographic showing the ocean zones:
Sunlight, Twilight, Midnight, Lower Midnight, and The Trenches. The page also includes videos showing: what happens to material at 100, 1000, and 10,000 meters down; the animals living in the Abyssal Plains (described in a lovely Scottish accent); and the story of Jacques Piccard and Don Walsh going down to the Mariana Trench in 1960. No one has been back there since, but director James Cameron
and Richard Branson
are among the contenders who are going to make a go of it. (Rumour has it that Cameron intends to be the sole person in the sub, while Branson is just financing a team.) Meanwhile, the Doer team
(backed by Eric Schmidt of Google), says it's all about the science and not just being first in this century's race. And there's even a yellow submarine for the rest of us
, if by "rest of us" one means "has $250,000 to spare for a single trip". Don't forget to click the links at the top of the infographic page to see everything.

Like a "modern-day pirate," 75-year-old Ray Ives has been diving for sunken treasure for decades. Wearing an ancient, bronze-helmeted diving suit, he searches the ocean floor and keeps a huge collection of marine salvage (including antique cannon balls, 'bottles, bells, swords, portholes and diving gear') in a shipping container "museum" at a British marina.

Obituaries editors probably belong by the sea. The cries of seagulls are their music, fading into infinity, and the light-filled sky bursts open like a gateway out of the world. The elderly gravitate there, shuffling in cheerful pairs along Marine Parade or jogging in slow motion past the Sea Gull Café, intent on some distant goal. Their skin is weathered and tanned, as if they have fossilised themselves in ozone to keep death at bay. They wear bright trainers, young clothes. But they have shifted to the shore here, or in Bexhill, or in Eastbourne, as if to the edge of life, and each flapping deck-chair reserves a waiting-place. Ann Wroe, obituaries editor of The Economist, muses on mortality and the sea
in the latest correspondent's diary
, a series of articles by various Economist writers. You can read the magazine's obituaries here
, including a recent one of former obituaries editor Keith Colquhoun

Long before Chelsea Piers was a sporting complex and the South Street Seaport a mall, the city was lined with active piers. The city's residents were amply employed by the shipping trade, but containerization needed more land than would ever be available in the city: Massive ports sprouted in Elizabeth and Newark, and ships disappeared from the city. Efficient cranes replaced longshoremen, and the time in port for ships shrank from about a week to about a day.
"The technology changed the geography," says William Fensterer, a chaplain who has been with SIH almost since its new building opened in 1964. "It doesn't look like On the Waterfront anymore," he adds. When he started out, he says, he would wander on foot from pier to pier in Manhattan and Brooklyn and board ships, with nary a guard in site. But those piers have largely vanished.
And along with them, the seafarer, once ubiquitous in New York, has become invisible.

In 2009, a remarkably gifted politician, confronting a remarkably difficult set of challenges
, will have to learn to say "No we can't"
, Guantánamo will prove a moral minefield
, economic recovery will be invisible to the naked eye
, governments must prepare for the day they stop financial guarantees
, we will judge our commitment to sustainability
, scientists should research the causes of religion
, we will all be potential online paparazzi
, English will have more words than any other language
(but it's meaningless), Afghanistan will see a surge of Western (read: American) troops
, Iran will continue its nuclear quest
while diplomacy lies in shambles
, the sea floor is the new frontier
, we should rethink aging
, (non-)voters will continue to thwart the European project
-- but cheap travel will continue to buoy it
-- though it has some unfinished business to attend to
, and a Nordic defence bond will blossom

Evidence of the "Milky Sea" --
The mysterious ocean glow described by Jules Verne in "20,000 Leagues Under the Sea" and observed by sailors has been confirmed by recent satellite photos
. On many occasions over the centuries, mariners have reported witnessing surreal nocturnal displays where the surface of the sea produces an intense, uniform, and sustained glow that extends to the horizon in all directions. Although such emissions cannot be fully reconciled with the known features of any light-emitting organism, these so-called "milky seas" are hypothesized to be manifestations of unusually strong bioluminescence produced by colonies of bacteria in association with a microalgal bloom in the surface waters. Because of their ephemeral nature and the paucity of scientific observations, an explanation of milky seas has remained elusive. Here, we report the first satellite observations of the phenomenon.
