Multi-Scale Sampling with Autonomous Systems for Coastal Ecosystem Research

This research project aims to establish a national littoral laboratory and deploy a real-time coastal ocean observatory with a data-assimilative coupled ocean-atmosphere forecast model. The project also focuses on improving nowcast and forecast skills through assimilation of remote sensing data and adaptive sampling. The scientific objectives include studying coastal upwelling, 3D structure and dynamics of upwelling centers, biological and chemical processes, and the effects of biology and sediment transport on ocean color and visibility.

  2. NOPP Objectives • Establish a National Littoral Laboratory • Deploy a Real-Time Multi-Disciplinary Coastal Ocean Observatory • Develop a Data-Assimilative Coupled Ocean-Atmosphere Coastal Forecast Model • Encourage Community Involvement Through an Open-Access Architecture

  3. NOPP Objectives • Operate the System in a Continuing Series of Coastal Predictive Skill Experiments 1998 - Improve Nowcast Skill • Assimilation of remote sensing surface data, and • Shipboard/AUV adaptive sampling subsurface data 1999 - Improve Forecast Skill • Improved surface, bottom and lateral boundary conditions • New turbulent closure schemes • Physical/bio-optical adaptive sampling with ships and AUV’s

  4. Scientific Objectives • Multi-Disciplinary Studies of Coastal Upwelling on a Highly Stratified, Shallow, Wide Shelf • 3-D Structure, Evolution and Dynamics of the Recurrent Upwelling Centers and their Interactions with Topography • Effects on Biological/Chemical Processes Including Phytoplankton, Zooplankton and Larval Distributions, and Hypoxia • Effects of Biology and Sediment Transport on Ocean Color and Visibility

  5. The Challenge “Shelf waters deeper than 3 meters and shallower than about 30 meters have often been ignored in the past because of the very difficult operating conditions and the complex dynamics, where the water is filled with turbulent boundary layers.” Ken H.
