Topsail Turtles

submitted by: dehartclark
Topsail Island, North Carolina is a northern nesting beach of threatened Loggerhead Sea Turtles. Here the residents have helped protect the turtles that visit the island during the nesting season. Beach walkers watch for turtle nests, pick up trash and report injured turtles. The island commerce has decided not to import new sand like most beaches, so the composition of the sand for incubation of turtle eggs doesn't change. The Karen Beasley Sea Turtle Rescue and Rehabilitation Center...

The Importance of Marine Picoeukaryotes and the Search for Lost Time

submitted by: dougramsey
Unicellular eukaryotes are responsible for a massive amount of photosynthetic carbon fixation in marine systems. The smallest among these fall within the “pico” size fraction (<2 micrometers in diameter), are broadly distributed – from coastal to open-ocean environments – and are highly diverse. Picoeukaryotes contribute a significant proportion of the biomass and primary production within this size fraction, often rivaling their cyanobacterial counterparts Prochlorococcus and...

Accessing the Metatranscriptome for Complex Marine Microbial Communities

submitted by: dougramsey
Sequencing the expressed genetic information of an ecosystem (metatranscriptome) can provide information about the response of organisms to varying environ mental conditions. Until recently, metatranscriptomics has been limited to microarray technology and random cloning methodologies. The application of high-throughput sequencing technology is now enabling access to both known and previously unknown transcripts in natural com munities. We present a study of a complex marine meta...

Ichnology for the 21st Century: Understanding the differences between continental and marine trace fossils, with implications to the diversity, distribution, and evolution of soil biota ; Department of Geological Sciences, San Diego State University, Seminar Series ; The study of ichnology has come a long way since its inception and it continues to evolve. In particular, progress is being made in understanding the implications of trace fossils in the continental realm and how they can be...

Canary in a Coal Mine (MWV16)

submitted by: MicrobeWorld
Coral reefs are dying a death of a thousand cuts and their disappearance threatens not only the incredibly diverse ecosystem that depends on them, but also human health and welfare. In this episode of MicrobeWorld Video marine scientists Ove Hoegh-Guldberg, Ph.D. , chair of marine studies at the University of Queensland in Brisbane, Australia, and Kiho Kim, Ph.D. , director of the environmental studies program at American University, explain the important relationship between microbes...

The Keeling Curve Turns 50

The inception of the "Keeling Curve," a history of atmospheric carbon dioxide levels, marked a key moment in American science history. The record began in March, 1958 at a small observatory on the top of Hawaii's Mauna Loa.

A NEW WORLD VIEW

A network devoted to recording the state of the oceans is nearing its full complement. Will it remain intact as its decades-long mission begins?

The Cloudmakers

Biological activity in the oceans might make the difference between clear skies and cloudy, Scripps researchers say.
