Time series are an essential tool for detecting the complex interactions among climate forcing, ecosystem structure and biogeochemical cycling. To date, there are relatively few sites around the world where detailed, high quality, interdisciplinary time series measurements of ocean biogeochemistry are long enough to begin to differentiate longer term climate trends from higher frequency dynamics, such as event to seasonal scale processes.

Meeting Objectives

There have been few opportunities for the OCB community to help define future research at the U.S.-supported time series sites. This workshop aims to: 

-          Provide a synthesis of ongoing research at US OCB sites,

-          Summarize knowledge gained on temporal variability and controls on key  ecosystem processes and biogeochemical cycles,

-          Highlight capabilities at each of the US OCB time-series sites,

-          Promote community input in identifying priority directions and

-          Develop new opportunities for future research at the existing ocean time-series. 

The committee welcomes participation from scientists of all career stages and members of the international science community. Students, particularly involved with time-series work, are encouraged to attend. Participants will explore the feasibility and impact of developing new research that may combine OCB time series sites, and provide input to the OCB program on how the time series programs can best continue to serve the oceanographic community and the public.

Science Themes and Workshop Structure

The major OCB science themes that will guide discussions during the workshop are:

  • Feedbacks and climate sensitivities of biogeochemical cycles and interactions with ecosystem structure.
  • Ocean carbon production, uptake, and storage.

The steering committee seeks participants from relevant OCB communities to conduct balanced and fruitful discussions. Plenary talks, centered around key findings obtained from time-series measurements, in particular coupling or decoupling of elemental cycles and production and export, will provide the backbone for some of the discussion.

Breakout group discussions will be focused on:

1) Prioritization of biogeochemical processes that may be climate sensitive, may be involved in feedbacks, or appear important to sustain or develop as components of time-series sampling;

2) Identification of important scales of variability associated with processes that couple (or decouple) elemental cycles, productivity, and export; and

3) Discussion of appropriate and suitable sampling platforms, technologies, and strategies for sustained observing of biogeochemical dynamics at the existing time series sites. 

Facilities at the East-West Center in Hawaii will limit the meeting size to approximately 50 participants. 

Application Deadline: April 21, 2010

The steering committee will assess both the number and breadth of expertise of registrants and make selections in order to meet the size constrains and keep discussion focused.
