Title: Internal Tides in the Ocean
Host: Xinfeng Liang
Abstract: Internal tides are ubiquitous in the stratified ocean and are believed to play an important role in driving ocean mixing and meridional ocean circulation. They are generated in the barotropic tide and bottom topography interaction, and transport the converted tidal energy over hundreds to thousands of km in the open ocean. Our understanding of internal tides based on field measurements is poor, mainly because field measurements are sparse in the ocean. Fortunately, great progresses have been made in observing internal tides by satellite altimetry, which detects the internal tide’s cm-scale fluctuations at the sea surface. The global maps of M2, S2, K1 and O1 internal tides are constructed by 25 years of satellite altimeter data. Their generation, long-range propagation, phase/group speeds, refraction, reflection, and convergence/divergence are examined. Internal tide energy is also estimated from its sea surface height amplitude. Mode-1 and mode-2 internal tides are separately resolved by satellite altimetry. It is suggested that internal tides can be used to monitor ocean heat content changes from small changes in their propagation speed by internal tide oceanic tomography (ITOT, similar to acoustic tomography). In the end, the global internal tide fields simulated by several numerical models are also discussed.

Title: Lake Okeechobee and coastal water quality: A brief history, current events, and an uncertain future
Host: Elizabeth Carnahan (Florida Sea Grant)
Bio: Dr. Lisa Krimsky is a faculty member with the University of Florida IFAS Extension and the Florida Sea Grant Program. Lisa is part of a team of five Water Resource Regional Specialized Agents located across the state to lead and support water resource extension education programs. Lisa’s efforts are focused primarily in southeast Florida with a focus on water quality in coastal and estuarine ecosystems. Her programs help solve water resource issues that are critical to the economic development and environmental protection in Florida. Lisa received her PhD in Marine Biosciences from the University of Delaware in 2008 and her BS in Environmental Science and Policy from the University of Maryland.

Title: Embedding zooplankton physiology into our understanding of the Biological Pump 
Host: David Murphy
Abstract:
Many zooplankton and nekton make daily migrations below the ocean’s euphotic zone and mixed layer. In the darkness of the “twilight zone” they respire and excrete, releasing surfaced derived CO2 and waste products into the midwater. Globally, these migrations account for 15 – 40% of the total organic carbon export from the surface to ocean interior, exceeding in many cases the carbon flux associated with passively sinking particles, while similar percentages have been reported for the nitrogen-related processes. These zooplankton also contribution to midwater fragmentation and repackaging of sinking surface material; this influences the attenuation of flux (nutrient transport) from the surface to the deep ocean. Variability in the vertical distribution and physiology of zooplankton can thus substantially affect community ecology and biogeochemical cycles in the open ocean. New advances in technology, including high-throughput molecular sequencing and ultrahigh resolution mass spectrometry, are providing innovative opportunities to investigate the details of how zooplankton both influence and are constrained by midwater (100 – 1000 m) processes. Leveraging the multi-decadal Bermuda Atlantic Time Series (BATS) and new collaborations among zooplankton ecologists, physical, microbial, and chemical oceanographers (BIOSSCOPE and EXPORTS), these new tools are enabling novel observations and analyses that have the potential to sharpen our understanding of the roles that zooplankton play in the midwater ecosystem. Current investigations are focusing on identifying the spatial/temporal distributions of organisms in the water column, how their physiology changes over daily time scales (via transcriptomic, proteomic and organismal level metrics), determining the composition of their excreta (including the use of metabolomics), and exploring how these factors collectively influence the microbial community and the cycling of organic matter.
