Shift work helps marine microbes share scarce ocean resources

With a low supply of and high competition for key nutrients, scientists have puzzled over the vast diversity of microbial species found in the open ocean. A new study shows that time of day is key, with species of marine microbes specializing in different shifts throughout the day and night.

Vitamin B-12, and a knockoff version, create complex market for marine vitamins

Vitamin B-12 exists in two different, incompatible forms in the oceans. An organism thought to supply the essential vitamin B-12 in the marine environment is actually churning out a knockoff version.

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.

Vitamin water: Measuring essential nutrients in the ocean

Oceanographers have found that archaea, a type of marine microbe, can produce B-12 vitamins in the ocean.
