UD alumna studies leatherback sea turtles in Costa Rica

It’s not every day that you get to see a creature that has been around for 110 million years emerge from the ocean and lay its eggs on the beach. Unless, of course, you’re like University of Delaware graduate Lauren Cruz, who spends her days in Costa Rica with the Leatherback Trust studying leatherback sea turtle nesting ecology.

Cruz, a 2013 graduate who studied wildlife conservation in UD’s College of Agriculture and Natural Resources, is tracking the demographics of the turtles that nest at Playa Grande and Parque Nacional de las baulas — which translates to the park of leatherback sea turtles — and spends her nights with a team patrolling the beach looking for nesting turtles.

Seahorse Heads have a ‘No Wake Zone’ That’s Made for Catching Prey

AUSTIN, Texas — Seahorses are slow, docile creatures, but their heads are perfectly shaped to sneak up and quickly snatch prey, according to marine scientists from The University of Texas at Austin.

“A seahorse is one the slowest swimming fish that we know of, but it’s able to capture prey that swim at incredible speeds for their size,” said Brad Gemmell, research associate at the University of Texas Marine Science Institute, which is part of the College of Natural Sciences. (more…)

NASA/WHOI Voyage Set to Explore Link Between Sea Saltiness and Climate

A NASA-sponsored expedition is set to sail to the North Atlantic’s saltiest spot to get a detailed, 3-D picture of how salt content fluctuates in the ocean’s upper layers and how these variations are related to shifts in rainfall patterns around the planet.

The research voyage is part of a multi-year mission, dubbed the Salinity Processes in the Upper Ocean Regional Study (SPURS), which will deploy multiple instruments in different regions of the ocean. The new data also will help calibrate the salinity measurements NASA’s Aquarius instrument has been collecting from space since August 2011. (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…)
