Iron fertilization less efficient for deep-sea CO2 storage than previously thought?
Ian Salter from the Alfred Wegener Institute and a team of international collaborators discovered that iron fertilization promotes the growth of shelled organisms. In a naturally iron-fertilized system in the Southern Ocean the growth and sinking of these phytoplankton grazers reduces CO2 deep-ocean storage by up to 30 percent. Ignoring this response could result in overestimating the marine CO2 storage capacity resulting from iron fertilization. The study is published by Nature Geoscience.

NASA eyes Post-Tropical Storm Nuri's winds, now to affect Alaska
NASA's newest Earth observing mission, the International Space Station-Rapid Scatterometer, or ISS-RapidScat provided a look at the winds within post-tropical cyclone Nuri on Nov. 5 and 6 as it moved parallel to Japan. Nuri has moved across the Pacific and is expected to bring hurricane-force wind gusts to Alaska's Aleutian Islands today, Nov. 7.

Harmful Algae
Nutrients that feed red tide 'under the microscope' in major study
The 'food' sources that support Florida red tides are more diverse and complex than previously realized, according to five years' worth of research on red tide and nutrients published recently as an entire special edition of the scientific journal Harmful Algae. The microbiology, physiology, ecology and physical oceanography factors affecting red tides were documented in new detail and suggestions for resource managers addressing red tide in the coastal waters of southwest Florida were offered.

Global Food Security
Understanding of global freshwater fish and fishing too shallow, scientists say
Inland fish have to make a bigger splash. What sounds counter-intuitive to an activity commonly perceived as quiet is the broad recommendation of scientists at Michigan State University recommending that small-scale fishing in the world's freshwater bodies must have a higher profile to best protect global food security.

Study shows benefits of being fat (but not too fat) for deep-diving elephant seals
Researchers using a new type of tracking device on female elephant seals have discovered that adding body fat helps the seals dive more efficiently by changing their buoyancy. The study looked at the swimming efficiency of elephant seals during their feeding dives and how that changed in the course of months-long migrations at sea as the seals put on more fat.

Synthetic fish measures wild ride through dams
A synthetic fish is helping existing hydroelectric dams and new, smaller hydro facilities become more fish-friendly. The latest version of the Sensor Fish -- a small tubular device filled with sensors that analyze the physical stresses fish experience -- measures more forces, costs about 80 percent less and can be used in more hydro structures than its predecessor, according to a paper published in the journal Review of Scientific Instruments.

Applications in Plant Sciences
Scientists replicate the tide with two buckets, aquarium tubing, and a pump
A design for a new, inexpensive tidal simulation unit enables researchers to investigate tidal marsh plant growth in a controlled setting. The unit costs less than US$27 to build, takes up less than two square feet of space, and does not require external plumbing; the protocol is available in the November issue of Applications in Plant Sciences. The system could be an important tool for researchers working to preserve and restore environmentally important wetlands.

Mussels on California coast contaminated with giardia transmitted from land-based sources
The pathogen Giardia duodenalis is present in mussels from freshwater run-off sites and from areas where California Sea Lions lounge along the coast of California, according to a team of researchers from the University of California, Davis. One of the G. duodenalis strains found is known to infect humans; the two others occur mostly in dogs and other canids. 'Thus, the detection of these assemblages implies a potential public health risk if consuming fecally contaminated water or uncooked shellfish,' says coauthor Woutrina Smith.
