There are a number of reasons for focused field campaigns• It is a successful approach to getting multidisciplinary research done to answer "tough" research questions• They can produce significant leaps forward in the science• Stimulates new model development, creating direct ties between modelers and data providers• Economies of scale, logistics, infrastructure, data systems

Longer term reasons include• Creating community, developing connections between different disciplines• Can form international ties

- Two-way exchange of science and technology between host country and US

• Trains students• Develops multidisciplinary data sets that can be used in future research

1) Historically, it has been difficult to develop meaningful interactions between terrestrial and ocean carbon cycle and ecosystem studies

a. There have been a number of successful large field studies in the past (FIFE, BOREAS, LBA, JGOFS, GLOBEC, WOCE, GEOTRACES)b. Generally conducted without land-ocean perspective, but NACP is an exception

2) However, land-ocean margins represent key areas where new insights regarding the carbon cycle may be gained by coordinated study;

a. Continental carbon budgets fail to account for a missing carbon term that may be transported through the coastal margin with uncertain magnitude and fateb. Changes in land ecosystem properties and land use/development may lead to changes in the export of carbon and other materials to the coastal ocean;c. Rise in sea level will profoundly alter coastal margins and may impact the associated processing and fluxes of carbon through the coastal margin;d. Coastal margins influence boundary conditions for continental atmospheric carbon budgets, yet their influence on atmospheric carbon is poorly understood;

3) Is their justification for a coordinated terrestrial-ocean carbon study?a. How should field program and campaigns be designed to address this?b. What would be the key satellite missions (e.g., GEO-CAPE, OCO) and associated data records that would support such a study?

i. Pre-launch preparationsii. Post-launch cal/val efforts

c. How could airborne measurements play a role in such a study?i. Lidar/Hyperspectralii. Radiometryiii. Airborne flux measurementsiv. Etc.

Charge to “Breakout Breakouts”

Core questions:

a. What does the carbon cycle and ecosystems community expect of this effort?

b. What are our biggest challenges in this area, and how do we address them?

c. Is our list of identified data records complete, or is something missing?

d. Does the carbon cycle and ecosystems community need to establish priorities for these and other activities, and, if so, how should they be established?

Veg 3D Field Campaign

DESDynI (Deformation, Ecosystem Structure and Dynamics of Ice)

A mission using InSAR and LIDAR to study hazards and global environmental change.

Mission objectives:• Determine the likelihood of earthquakes,

volcanic eruptions, and landslides.• Predict the response of ice sheets to climate

change and impact on the sea level.• Characterize the effects of changing climate

and land use on species habitats and carbon budget.

9

DESDynI Field Campaign Objectives

• Acquire data sets necessary to evolve the existing RADAR & LIDAR capability to map global 3-dimensional vegetation structure and biomass.

• To mature the algorithms required to meet DESDynI vegetation 3-D objectives.

• Develop datasets that could also support enhanced span of topics for future TE investigations.
