Layered Organization in the Coastal Ocean(LOCO)

Brief Program Overview

LOCO Program Objectives

• Describe the spatial and temporal scales of thin layers

• Understand the processes that lead to the formation, maintenance, and destruction of thin layers

Kinds of Thin Layers

Acoustical Bacterial Bioluminescent

Chemical Marine snow Microzooplankton

Optical Phytoplankton Physical

Toxins Zooplankton Bubbles (?)

LOCO Principal Investigators

• Brian Concannon / Jennifer Prentice (NAVAIR) – Mapping thin layers with shipboard LIDAR

• Tim Cowles (OSU)– Fine-scale planktonic vertical structure: horizontal extent and the controlling physical

processes

• Percy Donaghay & Jim Sullivan (URI)– 4-D Assessment of Thin Layer Structure, Dynamics and Impacts

• Margaret McManus (UHI) / John Ryan (MBARI) / Mark Stacey (UCB)– Quantify interactions of physical, biological and optical properties of thin layers

• Al Hanson (URI & SubChem Systems)– The Role of Nutrient Gradients in the Episodic Formation, Maintenance and Decay of Thin

Plankton Layers in Coastal Waters

LOCO Principal Investigators

• Van Holliday / Charles Greenlaw (BAE Systems)– Moored zooplankton acoustics; multi-beam fish / fish larvae sensor;

multi-frequency acoustical sensor for photosynthesis related bubble formation in thin layers

• Dave Fratantoni (WHOI)– Physical context for thin layers, measured with AUVs (Gliders)

• Lou Goodman (UMASSD) / Ed Levine (NUWC Newport)– REMUS - based turbulence measurements and mapping

• Jan Rines (URI)– Characterization of phytoplankton species (in and out) of thin layers

• Kelly Benoit-Bird (OSU)– Predator / prey interactions in thin layers; horizontal migration and

dynamics of of predator distributions
