Workshop Details
Iron at the Air-Sea Interface
06/10/2023 - 06/14/2023
Meeting Description:

The objective of this proposal is to organize and host a workshop that will address the most urgent open science questions related to biogeochemical cycling of iron (Fe) in the Earth System. The physicochemical speciation of Fe at the atmosphere-ocean interface and its cycling between the two oxidation states in soluble, colloidal, dissolved, amorphous, and crystalline forms, in the presence/absence of atmospheric/oceanic organic compounds and sunlight is one of the most uncertain components of Fe biogeochemical cycling. Yet, it received less attention than other “pure” oceanic or atmospheric processes, largely due to historic division of the related fields. Moreover, there are some exciting results in both atmospheric and oceanic fields that are often mutually beneficial, but not readily shared. This can lead to duplication of work, which in the best case delays the progress of finding the measurement and modeling solutions to handling iron speciation at the atmosphere-ocean interface. A small workshop will facilitate interactive discussion, often lost in big meetings. Participation in the workshop will be predominately by invitation. During the workshop, all the participants working on different parts of iron biogeochemistry (in the atmosphere and the oceans) and different working groups (i.e., FeMIP, GESAMP, ACE, etc.) will be engaged to explore what simultaneous information would be needed and what steps need to be taken to acquire such information, gain insight, and answer the most critical questions. One of the major goals of the workshop is to bring together established scientists and young researchers with new and different perspectives. To achieve this goal and to provide opportunities for professional interactions in a focused and productive forum, one third of invited researchers will be early career scientists (PhD students, postdoctoral researchers and young research scientists who received their PhD after 2010).

Motivation: Earth System Models (ESMs) now pay particular attention to interactions between the atmosphere and the ocean ecosystems, in response to the highlighted need for improved representation of climate forcing and feedbacks. These interactions have implications on trace gas exchange, bidirectional flux of particulates, and the overall global energy budget. Today all global ocean biogeochemical cycling models agree that accurate characterization of the ocean’s biological, chemical, and physical processes requires quantitative knowledge of atmospheric sources of aerosol soluble iron (sol-Fe), the fraction of total Fe that contributes to the dissolved Fe (DFe) inventory of the ocean. In addition to the direct forcing of climate through its effect on ocean productivity and atmospheric CO2 uptake, the atmospheric deposition of sol-Fe has been suggested to affect ocean ecosystem diversity and, as a result, climate feedbacks. Detailed atmospheric models for the delivery of sol-Fe from different aerosol sources (mineral dust, combustion, biomass burning), to the open oceans have been developed. However, mechanistic treatments of sol-Fe interaction with atmospheric dissolved organic matter or organics found in the ocean surface microlayer are still missing. Progress has been made in the treatment of different forms of DFe in ocean biogeochemical models, but especially a kinetic description of the processes (redox, organic complexation) that further affect iron solubility after deposition is still rudimentary. Without identifying and accurately describing Fe biogeochemical processes operating at the atmosphere-ocean boundary, ESM results cannot be used for confident projections of human induced effects on the carbon cycle and climate, or for exploring the effects of atmospheric nutrient deposition on phytoplankton abundance and diversity.


IMPORTANT: Participants should be aware that this workshop runs Saturday through Wednesday. Festival lodging rates will go into effect on the night of Wednesday the 15th. To avoid the rate increase, you should depart on the 15th. If your flight out of Montrose does not leave until Thursday the 16th, we suggest eating dinner in Telluride on the night of the 15th, taking the shuttle to Montrose after dinner, and staying at the Hampton Inn (970-547-4120) next to the airport. You will receive a discount at the Hampton Inn by saying you are a TSRC scientist.

We wish to ensure an intimate workshop setting, with no more than 20 to 25 participants. If you are interested in attending, but have not received an invitation, please contact the workshop organizer before registering.

Telluride Science is about expanding the frontiers of science, exploring new ideas, and building collaborations. The workshop schedule will allow for substantial unstructured time for participants to talk and think. All participants are expected to stay for the entire duration of the workshop. Scientists are encouraged to consider bringing family or friends. Telluride offers a number of options for children's camps (including Telluride Academy, Aha School for the Arts, and Pinhead Institute). There is more information on childcare, camps, and family activities on Telluride Science's website. Feel free to contact Telluride Science's staff to help with any planning and/or coordinating care.

Cancellation Policy: Cancellation Policy: Once a credit card has been charged, cancelled registrations will be subject to a cancellation fee. We will process registration fees beginning on January 15th, 2022. If a payment of registration fees has been processed, a $25 cancellation fee will be retained from a registration refund. Lodging fee payments will be processed 60 days prior to arrival, and a $100 cancellation fee will apply if cancellations occur after a lodging fee payment is completed. TSRC can only guarantee a refund for the remaining lodging fees if requested prior to the cancellation deadline that is specific to each lodging provider. TSRC always recommends that participants purchase travel insurance to protect against unforeseen, last-minute travel plan changes.
