Marine Plants Play Major Role in Phosphorus Cycling

Phosphorus is one of the most common substances on Earth. An essential nutrient for every living organism—humans require approximately 700 milligrams per day—we are rarely concerned about consuming enough of it because it is present in most of the foods we eat. Despite its ubiquity and living organisms’ utter dependence on it, we know surprisingly little about how it moves, or cycles, through the ocean environment. (more…)

Massive detector homes in on cosmic ray production

IceCube, an international collaboration involving University of Delaware scientists, is shedding new light on cosmic ray production.

Although cosmic rays were discovered 100 years ago, their origin remains one of the most enduring mysteries in physics. Now, the IceCube Neutrino Observatory, a massive detector in Antarctica, is homing in on how the highest energy cosmic rays are produced. (more…)

Rising Oceans – Too Late to Turn the Tide?

*Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere levels off.*

Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found.

The study combined paleoclimate records with computer simulations of atmosphere-ocean interactions and the team’s co-authored paper is accepted for publication in Geophysical Research Letters. (more…)
