The first in-person meeting of the Iso2k working group, a subgroup of PAGES 2k Network, will take place 14-15 May 2017 in Zaragoza, Spain, following PAGES' 5th Open Science Meeting.

Venue

The Consejo Superior de Investigaciones Científicas (CSIC, the Spanish National Research Council) offices in the Zaragoza City Center. Address: Plaza Emilio Alfaro Gracia, 2.

Please note this location is different from the OSM venue!

Logistics

The workshop is open but limited to 40 participants. Coffee and lunch will be provided both days. A workshop dinner will be held 14 May at 20:30 at La Reserva (C/ Cádiz, 10, 50004, Zaragoza).

If you would like to eat lunch or dinner during the meeting, you MUST fill out this form by Monday 1 May! This form gives a head count for lunch and dinner, your order for our group dinner (which has to be placed in advance), and info on dietary restrictions.

Background

Iso2k is creating a global database, to be finished in the coming months, of records of the stable isotopic composition of water (δ18O and δD). Iso2k will use the database to identify regional- and global-scale features in hydroclimate and atmospheric circulation during the past 2kyr and their relationship with PAGES temperature reconstructions. This effort is, as far as we know, the only active, global, multi-proxy hydroclimate database being constructed under PAGES2k/Hydro2k.

Iso2k has been meeting ~monthly via teleconference since it began in spring 2015.

Group members have identified a number of scientific questions that the database will be used to answer, including:

- How do water isotope proxy records capture changes in the tropical water cycle?
- Where and how well do the modern day temperature-hydrology relationships hold over the last 2k?

By May, we will be ready to analyze data from the Iso2k database to address these questions.

Goals

Iso2k has spent the past ~1.5  years assembling a database of O and H isotope based proxy records covering some part of the past 2,000 years. We're currently working on quality control of the "beta" version of the database. The goal of our meeting in Zaragoza is to evaluate patterns of climate and isotope proxies that are emerging from the Iso2k database. This meeting will be a very hands-on, active discussion of scientific results. In order to stimulate the most productive discussion possible, we are asking every participant to do a little legwork ahead of time. Participants have been placed into small "buddy groups" of people who share similar interests. Each group should come to the Zaragoza meeting with 1-2 plots/figures (per group) that they have made using the database. These figures can be very rough, and certainly don’t have to be pretty! We will build our discussion around them (see agenda).

At the end of these discussions, key points will be drafted to serve as the structure for a scientific paper. The second half of the second day will be dedicated to future planning and strategizing for Iso2k.

Registration

The Iso2k Team Meeting will be an active, science-focused workshop. As such, we expect meeting participants to actively participate in the Iso2k effort prior to and after the meeting, including helping with quality control, preliminary analyses, and/or data-model comparison.

If you are interested in joining us, please apply by filling out this form by 10 March. Feel free to distribute to colleagues who may be interested. Due to logistical reasons and to facilitate productive discussion, attendance will be limited to ~40.
