Oxygen Minimum Zones expanding

ST. PETERSBURG, FL - Recent research suggests that oxygen levels are declining, and oxygen minimum zones expanding, throughout the world's oceans as a result of climate change. Members of the Seibel lab have just returned from a month-long cruise aboard the R/V Sikuliaq in the Eastern Tropical Pacific studying the low-oxygen tolerance of marine animals. Zooplankton in this region display the lowest critical oxygen levels (highest tolerance) of any animals ever measured and live on the edge of oxygen limitation.

PhD student Liz Fahsbender selected for NSF EAPSI Fellowship in Japan

ST. PETERSBURG, FL - PhD student Liz Fahsbender was selected to participate in the highly competitive NSF East Asia and Pacific Summer Institutes (EAPSI) program, where she will study the viruses found in ticks alongside researchers at Hokkaido University in Japan this summer.

PhD student Michelle Masi collaborates with NMFS

ST. PETERSBURG, FL - On Oct 17, 2016, Michelle Masi successfully defended her dissertation entitled, "An ecosystem-based approach to reef fish management in the Gulf of Mexico". In collaboration with the National Marine Fisheries Service, she used an ecosystem model to evaluate potential harvest control rules for use in Gulf of Mexico reef fish fisheries management. Her results suggested that using an adaptive management approach has the potential to improve fisheries yields while simultaneously increasing abundance and biodiversity of the reef fish assemblage. Joining as members of her academic committee were Dr. Michael Schirripa of NOAA's Southeast Fisheries Science Center in Miami, and Dr. Isaac Kaplan of the Northwest Fisheries Science Center in Seattle. Michelle Masi is a PhD Candidate in the Marine Resource Assessment program. She was recently hired to a full-time stock assessment position at the Fisheries and Wildlife Research Institute in St. Petersburg, FL. 

PhD student to sail on IODP Expedition 379 to Amundsen Sea, Antarctica

ST. PETERSBURG, FL - CMS PhD student, Theresa King, has been invited to sail on International Ocean Discovery Program (IODP) Expedition 379 to the Amundsen Sea, Antarctica. This expedition will set sail from Punta Arenas, Chile in January 2019, and over the course of two months, will collect sediment records from the continental shelf and rise of the Amundsen Sea. These records will allow for a better understanding of West Antarctic Ice Sheet (WAIS) dynamics from the Paleogene through the Holocene. Such an understanding, correlated with global climate records, will illuminate the stability and sensitivity of the WAIS through time. As the WAIS is currently experiencing the largest amount of ice loss of Antarctica, the information gleaned from this expedition will be vital to improving modeling parameters and outputs of future climate and sea level conditions.

Aboard the D/V JOIDES Resolution, King will work as a Petrophysicist/Physical Properties Specialist. Upon returning to CMS, King’s research will focus on using the recovered sediments to reconstruct interactions between the ice shelf and warm waters on the continental shelf.

Recent Antarctic expeditions uncover clues to Antarctic ice sheet evolution and climate sensitivity

ST. PETERSBURG, FL - Since she was an undergraduate, Dr. Amelia Shevenell has been interested in how ocean and atmospheric temperatures influence Antarctica’s ice sheets in the distant and not-so-distant past.

For at least 34 million years, Antarctica has been partially or completely covered in ice. Plate tectonics positioned Antarctica over the pole more than 65 million years ago, and drove India, Australia, and South America northward during the breakup of the supercontinent, Gondwana. This tectonic break-up formed the Southern Ocean, which encircles Antarctica. The Antarctic Circumpolar Current now mostly isolates Antarctica from heat derived from lower latitudes, but not completely. South of the Polar Front, warm nutrient-rich waters formed in northern latitudes upwell, bringing heat to Antarctica’s ice sheets. Both modern and geologic observations indicate to Dr. Shevenell that oceanic and atmospheric warming influences Antarctica’s ice sheet stability. 

NSF funded research aboard the US ice-breaker R/V Nathaniel B. Palmer in 2014 is yielding new information on the role of ocean and atmospheric temperatures on East Antarctica’s ice sheet evolution.

By studying the marine geologic record close to Antarctica’s ice sheets, researchers seek to understand the mechanisms by which glaciers retreat when climates were as warm or warmer than present. During the 2014 expedition to the Sabrina Coast, East Antarctica, Shevenell and her collaborators discovered that the East Antarctic Ice Sheet is more sensitive to climate changes than previously thought. This is important because global sea level would rise 53 meters (174 feet) if the East Antarctic Ice Sheet melted completely. More realistically, ice melt from the most sensitive regions of East Antarctica could raise global sea levels ~19 meters (~60 feet). Glaciers along the Sabrina Coast are presently retreating and could contribute 3–5 meters (9–16.5 feet) of global sea level rise in a warming world.

Shevenell, USF graduate students, and collaborators collected evidence that ice expanded to the Sabrina Coast in the early-to-middle Eocene, much earlier than is traditionally accepted. They discovered deep channels carved into sediments and evidence for least 11 glacial advances and retreats across the continental shelf. These results indicate variability of regional glaciers may have been enhanced by large amounts of meltwater during the Oligocene and Miocene, geologic times when climate was warmer and atmospheric CO2 higher than at present. About seven million years ago as global climates cooled, regional glaciers expanded, stabilized, and were not influenced by meltwater. These results indicate that the East Antarctic Ice Sheet has long responded to climate variability. If meltwater increases as with continued warming, Antarctica’s ice sheets might respond more dynamically than expected.

In early 2018, Dr. Shevenell will return to Antarctica aboard the International Ocean Discovery Program (IODP) drillship, the JOIDES Resolution. Dr. Shevenell and her USF CMS Ph.D. student, Imogen Browne, will work with an international team of scientists to drill sites in the Ross Sea, which will enhance understanding of Antarctica’s ice sheet evolution over the past 20 million years. This cruise is particularly exciting because Dr. Shevenell has worked for over a decade on proposing and planning this Expedition.    

As researchers explore Antarctica, more data is generated that can be plugged into ice and climate models to improve our collective understanding of ice sheet response to ongoing warming. Model improvements will ultimately enable scientists to make accurate estimates of regional sea level rise, which are critical to policy makers, particularly those in low-lying regions, such as Tampa Bay.

Remote Sensing, a necessary tool for studying biodiversity at effective scales

ST. PETERSBURG, FL - From local to global and micro to macro, the applications of remote sensing are integral to understanding biodiversity across regions and filling the data gaps that exist between them. 

Dr. Frank Muller Karger and his group at the Institute for Marine Remote Sensing collaborate with a larger network of scientists and resource managers to catalog biodiversity as it has never been done before:  with consistency of data from region to region and at scales that reveal the important connectivity among the gradient of marine habitats.

Sanctuaries Marine Biodiversity Observation Network (Sanctuaries MBON) is part of a global consortium of BONs that are building web portals of real-time and historical data through which scientists and environmental resource managers can assess the ecological well-being of the region they are tasked with studying, maintaining or improving. 

On-going bimonthly cruises in the Florida Keys National Marine Sanctuary (FKNMS) are conducted by NOAA AOML scientists and members from IMaRS to gather a suite of water quality data.  Pairing water samples with satellite observations, IMaRS member Megan Hepner uses GIS maps to display biodiversity of coral reef fishes along the entire reef tract of the FKNMS.  Simpson and Shannon diversity indices – statistical methods used to classify ecosystem integrity and resilience – show that greater diversity is found in the Lower and Upper Keys than in the Middle Keys.  Dr. Muller-Karger and assistant Dr. Enrique Montes oversee the assimilation of the sampling efforts and observations into the Sanctuaries MBON research initiative. 

Tools like infographics will be a key point of interaction on the sites for both resource managers and members of the general public to learn about the biological composition of some protected ecosystems and any changes in diversity over time.  GIS maps hosted on the MBON web portal provide further spatial and temporal visualizations of ecosystem health and diversity in three National Marine Sanctuaries:  the Florida Keys, Monterey Bay and Flower Garden Banks. 

An additional layer of sampling within the MBON initiative is environmental DNA (eDNA).  The Marine Genomics Lab led by Dr. Mya Breitbart at the USF College of Marine Science is responsible for analyzing seawater samples for trace amounts of genetic material left behind by anything from microbes to whales.  New methods allow for fast, affordable interpretation of the DNA present in concentrated water samples.

The size, depth, and unforgiving surface conditions of the ocean make it impossible to continuously monitor conditions from all desired locations.  Satellite-based remote sensing provides solutions at exceptional spatial and temporal scales.  Careful groundtruthing is required to match sea surface conditions to the data derived from sensors orbiting the earth, and once that is accomplished, the result is unparalleled coverage of terrestrial and oceanographic ecosystems. 

Analysis of satellite data has allowed researchers from IMaRS to study phytoplankton blooms off the Texas coast in the wake of Hurricane Harvey, explore outbreaks of Dengue fever in the Caribbean, and improve wetland mapping methods for coastal areas.  In addition, the lab is improving characterization of the impacts to coastal areas from red tides, storm-generated sediment plumes, water quality events, and land cover changes. 

Concurrent satellite observations of biological and physical variables from around the world allow observation networks to map the data in near real-time.  Some records span nearly three decades, and without these long term measurements, our understanding of changes throughout time would be lacking over much of the surface of the earth.  The list of global measurements includes:  vegetation biomass (land and ocean), winds, currents, waves, rainfall, cloud cover, land topography, and more.  As Dr. Muller Karger states, “This allows us to see how biological processes on land and in the ocean react to, or in some cases modify, environmental variables that force them.”

Understanding diversity of life in the oceans is crucial to managing and preserving these resources, and the use of remotely sensed data enables the study of biodiversity on the proper scales.

SALSA - C and life in Antarctic subglacial lakes

ST. PETERSBURG, FL - NSF has funded USF College of Marine Science researchers to probe the nature of organic carbon in the water column and the sediment beneath subglacial Lake Mercer in Antarctica. The lake sites beneath over 1 km of ice and is episodically drained and filled by subglacial flow of water from the Mercer Ice Stream. USF researchers are part of an international group that will probe the lake for life after accessing it through the thick ice sheet. Water chemistry, sedimentary microbes, and the nature of the organic carbon within the sediments will be targeted for information about how life thrives and how carbon is cycled in these remote, isolated ecosystems. Of fundamental importance is analysis of whether marine carbon sources are the basis of life in these lakes as they may have had past incursions of marine water.
