Feb.: New species of deepwater coral reported off S. California. The black coral was discovered by submersible at 90 to 220 m depths, not very deep in terms of deep-sea biology, but deep enought to have been undiscovered until now. Pictures are available at a NMFS/NOAA website.
(a) Feb.: Foraminifera discovered in sediments of the Mariana Trench: in the ocean's deepest sediments, these protists appear to be thriving under 1000 atm of pressure. Foraminifera (forams for short) are unicellular; they build shells of CaCO3 although the Marianas species are said to be soft-walled. As eukaryotes, forams are advanced cells with nuclei and other organelles, and thus do NOT represent one of earth's earliest life forms, as erroneously stated in some articles (the earliest life forms were PROKARYOTES--archaea and bacteria). Forams may, however, represent one of the earliest EUKARYOTIC life forms. Foram remains often dominate deep-sea sediments elsewhere, and can be converted into limestone (indeed, the Great Pyramids of Egypt are built out of foram limestone).
(b) Feb.: Are some so-called COLD SEEPS not actually SEEPS? Geologist Charles Paull at MBARI has found evidence that some "seeps" in the Monterey Canyon of California are not sites of seeping water with sulfides.

The Lost City (see news story #7 in year 2001, below) on the MidAtlantic Ridge is a hydrothermal vent area that is quite different from other vent sites, having little sulfide and more hydrogen and methane. Note that the online news story has a significant ERROR: it says that microbes at other vents use carbon dioxide as an energy source. This is false. Carbon dioxide is a carbon source for producers to make sugar. Another source of this article is here.
5(b) March: Researchers sequence genome of deepsea bacterium in hopes of explaining pressure adaptations: Bartlett and colleagues at Scripps discovered that a deepsea photobacterium may have 2 sets of genes--one for high-pressure and one for lower pressures (Science, Mar. 4 issue).

June: A New Zealand-USA joint expedition is studying undersea volcanoes in the South Pacific, with many startling discoveries.
June: How does life in the deep get sufficient food? A new study by Robison and colleagues at MBARI finds that mucus "sinkers" are a major source. Sinkers are sloughed-off mucus nets of larvaceans--midwater animals related to benthic sea squirts. See the article in the June 10, 2005 Science.
June: Microbe that uses hydrothermal-vent light to photosynthesize reported: Beatty et al. (in the June 28 Proc. Natl. Acad. Sci.

Lovley and colleagues ( Science , Aug. 15 issue), who later reported that these microbes use IRON as an energy source and produce MAGNETITE as a result. Magnetite is the naturally magnetic mineral that humans first used to make compasses.
22. Oct. 23: The Census of Marine Life is a decade-long project (involving 53 coutries) that hopes to catalogue as many marine species as possible. New species are being found routinely, including new species of deep-sea fish . See also this CBS News Story .
23. Nov. 6: Jellies are turning out to have a far greater role in ocean ecosystems than previously suspected, especially in the deep sea.The 6-Nov-03 issue of Nature (vol. 426, pp12-14) has a news feature on "Close encounters of the jelly kind" describing the latest research with submersibles, etc. An example of a newly discovered deep-sea jelly can be found in this Zootaxa article .

5. First exploration of a deep Seamount : From May 17-24, an expedition led by MBARI conducted the first detailed study of a seamount (undersea mountain)--the Davidson Seamount/volcano off central California. The life found includes flytrap anemones, frogfish, mysterious rare eels such as a halosaur. See the NOAA website . or the CBS newstory on the discovery of giant coral and mystery mollusks .
6. New undersea mountains discovered; call for a new era of exploration. Incredibly, previously unknown volcanoes and seamounts as high as 2500 m (8000 ft) were recently found in the South Pacific. See Science 24-May-02 p. 1386. At an international meeting in Mid-May, oceanographers from around the world called for a new international effort to explore the undescribed areas of our planet.
7. "Original" hydrothermal vent disappears: the so-called Rose Garden, the very first deepsea vent with giant tubeworms ever discovered, has disappeared, probably destroyed by fresh lava. Found in 1977, the Rose Garden revolutionized our ideas about life in the oceans. See Science News 6-18-02, p.382, or the Discovery Channel news site .
8. Deepsea and shallow reefs formed by microbial oxidation of methane: In the 9-Aug-2002 issue of Science (p.1013), Michaelis et al. discuss how microbes may play a role in forming carbonate rocks and reefs by this process: CH4 (methane) + SO4 + Ca --> CaCO3 (rock) + H2S +H2O
9. Expedition explores massive gas hydrates off Oregon : a deepsea drilling project was completed in early September to assess gas hydrates off the Oregon coast. These are deposits of frozen methane that contain (in total) more energy than all known oil deposits (see below for more information on these deposits).
10. Undersea montoring network funded for Monterey Bay: Quote from the press release : "...the network will consist of undersea cables and docking stations to provide power and high-speed data links for a variety of oceanographic devices.....this network will allow real-time, continuous, long-term monitoring of conditions beneath the surface of the bay." This includes the deepsea, as one cable will be at 4000ft (1200m). See also News Item 1 under year 2000 below.
11. Naked retinas of hydrothermal-vent crabs may have evolved to detect the weak light produced by the vents. Jinks et al. report in Nature 7-Nov-02 (p. 30 and 68) that the larval crabs, which live in the plankton and not at the vents, have normal compound eyes, but as the animals mature, the eyes become non-optical amorphous naked retinas. These cannot form images but may have much better ability to detect faint light.
12. Giant gelatinous deepsea octopus , the largest known of this type of animal, was trawled up in March 2002 off New Zealand. Read about it and see a photo at the BBC news website .
13. Whipnose anglerfish in the deep was caught on video, surprisingly swimming upside down , probing the sediment with its long dorsal fin (Oct. 2002). See Science News 162:262 , or the original video at WHOI Deepsea Observatory site (look for "gigantactinid" fish).
14. Oil tanker sinks to the abyssal plain off Spain (19 Nov 2002). Lying at 3.5km deep, the wreck of the Prestige tanker caused a massive oil-spill disaster on the coast of Spain and France. Plans are being made to pump the remaining oil from the wreck, from a depth never before attempted. See New Scientist 14-Dec.-02 p.15.
15. Gas hydrates (frozen natural gas and water) are found in huge quantities in deepsea sediments. New studies ( Nature 12-Dec-02 p.622 and 656) suggest that some of these deposits may melt (due to global warming) and escape the seafloor along faultlines. This is of concern since natural gas (methane) is a far more potent greenhouse gas than CO2.
16. Mysterious deep-sea sound recorded again in June 2002: first heard in 1997 on the US Navy's deep-sea submarine-tracking hydrophone network, this mysterious sound from the abyss is thought to be from a huge unknown animal.

• New type of hydrothermal vent at the Lost City is described in detail in the July-01 Nature p.127 and 145 . This site is unique because the vents are on old seafloor rather than new, and because spires and chimneys are carbonate rather than sulfide deposits found at other vents. The initial discovery was reported earlier--see item #5 in 2000 below.
• Amazing microbes that eat methane : bacteria capable of using methane in the absence of oxygen have been described at methane seeps in the deepsea off N. California. Methane trapped in deepsea sediments may be the dominant hydrocarbon energy source on earth, but it was previously thought that no microbes could use it without oxygen. See 20-July-01 Science , p. 418 and p484 . See my Methane Seeps page for details on this California site.
• Hot-vent microbe decoded : Diversa Corporation has deciphered the complete genetic code of Pyrolobus fumarii , a microbe that lives at the hottest known temperatures (up to 113 degrees C), 3.5 km deep in hydrothermal vents in the Atlantic. 90% of the microbe's 2000 genes have not been found in other microbes, and may have industrial applications.

• Hydrothermal-vent bacteria may lead to better sunburn protection : New Scientist 3-Nov-01 reports that a French company is studying compounds from hydrothermal-vent bacteria that might protect human skin from damaging chemicals generated by excess sunlight exposure. The bacteria use these compounds to protect themselves from damaging free radicals generated at the vents.
• Hydrothermal-vent worm larvae are not heat-adapted : Science News 24-Nov-01 and 18-Oct-01 Nature report on a study by Gaill et al. on larvae of the vent worm Alvinella . The adult worm lives between 20 and 80 degrees C, but larvae only tolerate 2 to 14 degrees. At 2 degrees--the typical deepsea temperature away from vents--the larvae become dormant, and in this state they probably drift until encountering a warmer location.
• Weird deepsea squid with spaghetti-like arms that bend like having elbows, and sporting very large fins, has been spotted over the years, but never captured. It lives at 2,000 meters and deeper. The existence of this elusive species has now been documented by Dr. M. Vecchione of the Smithsonian, by collecting reports and photos from researchers and oilrig divers. See.

10. Noah's (& Gilgamesh/Utnapishtim's) Flood in the Black Sea? Pioneering deepsea explorer Bob Ballard has found evidence--remains of buildings in the sea bottom mud--that a catastrophic flood occurred in the Black Sea 7000 yrs ago. Initial evidence for this flood was originally found by W. Pitman and W. Ryan, who suggested it could be the source of the nearly identical babylonian (Gilgamesh/Utnapishtim) and biblical (Noah) legends of a great flood in the mideast (see their recent book, Noah's Flood : The New Scientific Discoveries About the Event That Changed History ).

See Science v.283, p.831, or New Scientist 13-Feb-99 p.19. The Jan. 9, 1999 issue of Science News reviews the evidence (p24). Also see 1998 news below for other articles and links.
    For recent evidence AGAINST this hypothesis, see the 8-Jan-99 issue of Science (p.155 and 220). Galtier et al. extrapolate thermal stabilities of ribosomes to ancient archaebacterial ancestors, and conclude they could NOT have worked in hydrothermal vents.
17. DEEP-SEA REPRODUCTION: Fujiwara et al. ( Deep-Sea Research 45:1881, 1998) document that elevated temperature can trigger spawning in cold-seep clams at 1,100 m deep; cues for reproduction in the deep see have been largely undiscovered before this.

19. Life in Deep-sea Low-Oxygen Zones is described by L.Levin in the Sept.-Oct. 2002 issue of American Scientist .Large areas of the deep sea have very low oxygen, due to 1) the lack of light for photosynthesis; 2) low circulation of oxygenated water from the surface, and 3) large amounts of decaying organic material falling from the surface waters (the decaying process uses up oxygen). The article describes what kinds of life can exist in these areas.

For more information on the worms, see New Scientist "Extreme Worms" article, July 25 '98. And Science News 14-Nov.-98 reviews the occurrence and potential human of the vast amounts of methane hydrates in the deepsea and beneath the surface. A general description these hydrates can be found at the USGS Gas Hydrates-New Frontier Page.
4. Origins of Life: Did life first evolve on earth at the hydrothermal vents ? Does this give clues to possible life on other worlds such as Europa? For a recent perspective on this, see Science , Apr. 1, 1998; Science July 31, 1998 (p.627&670). Also: in July '98, C. Huber and G. Wachtershauser demonstrate that minerals of hot springs may have catalyzed the first prebiotic protein synthesis ( Science 31-July-98, p627). In Sept. '98, researchers from the Carnegie institute reported ammonia, a key building block of life, at the vents (news story: Science , 25-Sept-98, p1936; article: Nature late Sept. '98).
5. Chlorophyll in Eyes of Deep-Sea Fish : R. H. Douglas et al. report ( Nature 4-June-98, p423; and New Scientist 6-June-98, p16) that midwater dragonfish have chlorophyll in their retinas that help them see red light. Red light normally does not exist in the midwater twilight as red wavelengths are absorbed strongly by water (and blue weakly, hence the ocean's color). Thus most deep-sea animals have lost the ability to sense red. But dragonfish have photophores that can make red light, which they use to illuminate prey. This allows the dragonfish's light to be virtually invisible to all but itself (a "sniperscope").
6. Chemistry and Biology of the Oceans : The July 10, 1998 issue of Science has a special section on this topic, which includes deep-sea vents.
7. Fawlty Towers--July 1998: Researchers with the black-smoker expedition sponsored by the American Museum of Natural History, the Univ. of Washington, and NASA, retrieved an intact hydrothermal-vent smoker chimney (from the "Fawlty Towers" site).

8. Underwater Avalanches : In the Mar. 26, 1998 issue of Nature , Rothwell and colleagues report detecting evidence of giant landslides that have drastically altered abyssal plains. These may be triggered by gas hydrates (see 1997 news for more on these hydrates).
9. Whale Falls : At the Feb. '98 Ocean Sciences meeting, Craig Smith of U. Hawaii reported that whale carcasses sinking to the deep provide a sudden feast for a variety of abyssal animals--hagfish, crabs, sharks that eat the remains, and worms, mussels and others that live off bacterial decomposition and chemosynthesis. The carcasses become a temporary habitat with more species than a hydrothermal vent. Reported in Science Vol 279, Feb. 27, 1998
10. How hot can animal life live? In Feb. '98 Cary et al. report evidence that a hydrothermal vent worm can tolerate hotspring water up to 80 o C in the deep sea (though others have since challenged the evidence). See World's most Heat-tolerant animal article or the Feb. 5, 1998 issue of Nature .
