Ocean current in Gulf of Mexico linked to red tide

13.01.2016

Results can help provide warning of red tide conditions in Florida's coastal regions

A new study found that a major ocean current in the Gulf of Mexico plays an important role in sustaining Florida red tide blooms. The University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science research team suggest that the position of the Loop Current can serve as an indicator of whether the algal bloom will be sustained, and provide warning of possible hazardous red tide conditions in coastal areas.


Toxic Karenia brevis blooms (commonly known as Florida red tides) occur often on the West Florida Shelf. These harmful algal blooms are hazardous to marine life as well as to humans (through neurotoxic shellfish poisoning or aerosolized toxins, which cause respiratory distress).

Florida red tide is a harmful algal bloom produced by the dinoflagellate Karenia brevis that causes respiratory impairment in humans and marine life, and is responsible for shellfish poisoning.

The researchers collected data of Karenia brevis concentrations, river outflows, wind conditions, and sea surface heights to study the physical conditions during periods of large Karenia brevis blooms and periods of no bloom. This research looked at the continuation of a bloom and not the formation of a red tide bloom.

They found that when the Loop Current is in a northern position, it allow a bloom to continue when other conditions were favorable, but when in a southern position a bloom could not be sustained. The Loop Current, which enters the Gulf of Mexico through the Yucatan Straits, is one of the most important features in the Gulf ocean circulation system.

"Knowing the approximate position of the Loop Current can be an indicator if a bloom will be sustained, and provide a warning for possible hazardous conditions," said UM Rosenstiel School Ph.D. student Grace Maze, lead author of the study.

The study, titled "Historical Analysis of Environmental Conditions During Florida Red Tide" was published in the Dec. 2015 issue of the journal Harmful Algae. The study's authors include: Maria J Olascoaga and Larry Brand of the UM Rosenstiel School.

The Oceans and Human Health Center at the University of Miami Rosenstiel School supported the project through a National Science Foundation grant and Gulf of Mexico Research Initiative funds provided by the Consortium provided for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE).

Im Focus: Thousands on one chip: New Method to study Proteins

Since the completion of the human genome an important goal has been to elucidate the function of the now known proteins: a new molecular method enables the investigation of the function for thousands of proteins in parallel. Applying this new method, an international team of researchers with leading participation of the Technical University of Munich (TUM) was able to identify hundreds of previously unknown interactions among proteins.

Im Focus: 3-D printing produces cartilage from strands of bioink

Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints, according to a team of engineers. "Our goal is to create tissue that can be used to replace large amounts of worn out tissue or design patches," said Ibrahim T. Ozbolat, associate professor of engineering science and mechanics. "Those who have osteoarthritis in their joints suffer a lot. We need a new alternative treatment for this."

Cartilage is a good tissue to target for scale-up bioprinting because it is made up of only one cell type and has no blood vessels within the tissue. It is...
