MOOS Science Experiment 2004John Ryan

MOOS is an integrated array of observing resources and infrastructure being developed to advance ocean science and its methods. It includes:

•mooring systems

•cabled observatory systems

•autonomous underwater vehicles

•instrumentation software infrastructure

•shore-side data system

What is MOOS?

Application, Demonstration, Development

Application of advanced observing system technologies to pursue cutting-edge science •Demonstration and testing of evolving technology •Development of observatory concepts and capabilities:

•Preparation for the experiment guides development efforts toward coherent scientific & technological achievements •Execution of the experiment tests observing system capabilities in realistic and demanding ways.

What is a MOOS Science Experiment?

• Major science drivers form soil • Roots and trunk are science/engineering (sciengineering?) efforts • Branches and leaves are technology development pathways that take

in nutrition from the roots and trunk and light and fresh air from the outside • MOOS Science Experiments are like fruits that grow from application of evolving technology at the forefront of scientific disciplines and that house seeds for further growth • Interesting and strange birds may land on the tree and fertilize the soil below, or they may eat the fruit and spread the seeds elsewhere

•Iron as ecosystem regulator •Phytoplankton ecology •Bioluminescence ecology •Frontal dynamics •Multi-platform sensing •Use of real-time data

MSE Process Details cont…

The intersection of major science interests with emergent technological capabilities forms a core around which experimental opportunities, goals, and plans spin.

The science frontiers envisioned for MOOS took shape during the 1999 MOOS Workshop and are detailed in the report "The Future of MBARI Ocean Observing Systems." The MOOS functional requirements document built upon these interests that span all oceanographic disciplines from air-sea interface to seafloor.

Define Science

•Refine Science

•Specify a Design


We found a primary region of interest based primarily on details of scientific interests (next section). However serviceability is key. During early stages of the process there was a balance of healthy imagination of possibilities and realistic expectations of resources.

Because we sought to build the science around a single mooring location, it was essential to consider overlap between scientific motivations and limits of the new MOOS capabilities, e.g. the spatial scale of connected benthic nodes relative to the scales of processes.

For each of the interdisciplinary science frontiers sighted for MSE 2004, we refined science goals and plans in focus group meetings and reports that detailed the science, questions and hypotheses, measurements required, and uses of emergent MOOS capabilities.

• Upper/mid-water column and pelagic-benthic coupling • Lower canyon and seafloor • Seep processes and chemosynthetic biological communities • Seismic studies

Refine Science


•Define Science

•Choose a Region

•Refine Science

•Specify a Design


This effort is closely coupled with the refinement of science goals and plans.It includes:

• Specifying power and communications for instruments that will be supported on the mooring • Detailing uses of MOOS hardware and other complementary observing resources • Specifying data management goals, especially with regard to connectivity (from verification of proper instrument functioning to event response) • Developing concepts of operation

• Flux of organic carbon to the seafloor

• Carbon flux from surface to below the euphotic zone may be strongly enhanced by current meanders in the zone where the mooring will reside.

• Carbon flux via Monterey Canyon to the fan passes through a very steep meander of the canyon: Shepard Meander.

Dynamics and ecology of the Coastal Transition Zone (CTZ)

Where recently upwelled waters flowing seaward meet the California Current, there are transitions in the biological communities, and transport processes strongly influence the fate of upwelling system productivity (pelagic-benthic coupling).

Upper Water Column - Background

How do we define the CTZ?

MSE 2004 Science

1. What is the magnitude of vertical flux from the pelagic to the benthic environment

2. How does it depend upon zone (recently upwelled water shoreward of the first transition versus aged upwelled water between the first and second transition)?

3. How do plankton assemblages differ between different zones and how do different assemblages influence export of biomass from the upper water column to the seafloor?

4. Does subduction in meanders enhance flux to the seafloor or are they remineralized and transported back into the upwelling system?

5. If frontal processes do enhance flux to the seafloor, how do these fluxes compare with integrated fluxes over larger non-frontal regions?

Canyon & Seafloor - Background

•Monterey Canyon is the largest submarine canyon incising the continental margin of western North America, and undoubtedly plays a large role in the transport of sediment and carbon from inshore habitats to the abyssal plain.

•While its role in material transport is certain, we know little about the rates, variability, and processes dominating material transport, or the influence of lateral carbon transport on the biology and ecology of the canyon ecosystem.

The chosen site is not ideal for seismic studies, however seismic measurements and testing of connectivity would be valuable. Placement of a seismometer on a BIN is dependent upon being able to locate on a flat region adjacent to the canyon.
