In early August of this year, University of Washington biologist Peter Ward encountered an example of the extremely rare nautilus Allonautilus scrobiculatus. Considered by Ward potentially one of the rarest species in the world, not a single one has been seen since Ward's first expedition over three decades past in 1984. Read about his latest expedition on EurekAlert!.

NASA data shows Hurricane Ignacio's very cold cloud tops indicate quick strengthening
When cloud top temperatures get colder, the uplift in tropical cyclones gets stronger and the thunderstorms that make up the tropical cyclones have more strength. NASA's Aqua satellite passed over Hurricane Ignacio and infrared data revealed cloud top temperatures had cooled from the previous day.

To track winter flounder, UNH researchers look to ear bones
Researchers at the University of New Hampshire are turning to an unusual source -- otoliths, the inner ear bones of fish -- to identify the nursery grounds of winter flounder, the protected estuaries where the potato chip-sized juveniles grow to adolescence. The research, recently published in the journal Transactions of the American Fisheries Society, could aid the effort to restore plummeting winter flounder populations along the East Coast of the US.

Intensity of desert storms may affect ocean phytoplankton
Scientists at MIT, Columbia University, and Florida State University have determined that once iron is deposited in the ocean, it has a very short residence time, spending only six months in surface waters before sinking into the deep ocean. This high turnover of iron signals that large seasonal changes in desert dust may have dramatic effects on surface phytoplankton that depend on iron.

Fishermen discards could increase prevalence of turtle disease in Turks and Caicos
The team surveyed cases of green turtle fibropapillomatosis disease, which creates unsightly pink tumors on the turtles' flesh. Although benign, they can impede turtles' vision and movement, as well as feeding, swimming and organ function. The virus is not thought to be dangerous to humans. Over two years, around 13 percent of green turtles found in waters had the disease. In contrast, fishermen did not land any diseased turtles during this period, even though they were fishing in areas where diseased animals were prevalent.

What would a tsunami in the Mediterranean look like?
A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published Aug. 27 in Ocean Science, an open-access journal of the European Geosciences Union.

Data backs limits on deep-sea fishing by depth
Researchers reporting in the Cell Press journal Current Biology on Aug. 27 have evidence in support of a clearly defined depth limit for deep-sea fishing in Europe. The findings come just as the European Union considers controversial new legislation to manage deep-sea fisheries, including a ban on trawling below 600 meters.

This week from AGU: Mars' ice, Earth's mantle & 5 new research papers
Just beneath Mars' dirt surface, or regolith, researchers found an enormous slab of water ice, measuring 40 meters (130 feet) thick, and covering an area equivalent to that of California and Texas combined, according to a new study published today in Geophysical Research Letters.

DNA sequencing used to identify thousands of fish eggs
Using DNA sequencing, researchers have accurately painted a clear picture of fish spawning activities in a marine protected area and have created a baseline for continuing studies on the effects of climate variability on fish populations. Scripps Institution of Oceanography at UC San Diego researchers collected 260 samples off the Ellen Browning Scripps Memorial Pier over a two-year period and used DNA barcoding to accurately identify over 13,000 fish eggs.

Lab experiments question popular measure of ancient ocean temperatures
The membranes of sediment-entombed archaea are an increasingly popular way to determine ocean surface temperatures back to the age of the dinosaurs. But new results show that changing oxygen can affect the reading by as much as 21 degrees C.
