Ocean Acidification

Workshop: Best practices for Durafet-based ocean and laboratory pH time-series

Venue: Laboratoire d’Océanographie de Villefranche, Villefranche-sur-Mer, France

Dates: 11-12 September 2017

Hosts: Dr. Lydia Kapsenberg, Samir Alliouane

We are pleased to announce a summer workshop on Honeywell Durafet pH sensor technology for seawater pH time series. Two Durafet-based sensors will be covered: SeaFETs for ocean pH time-series, and Durafet arrays for use in experimental systems in the laboratory. Durafet arrays greatly alleviate efforts for documenting pH during laboratory ocean acidification experiments. Durafet arrays can also be integrated in existing experimental systems to enable advanced experimental design (fluctuating and multi-driver experiments).

The two-day workshop will cover the principles of Durafet technology and best-practices for (1) sensor setup, (2) deployment, (3) calibration, (4) quality control, (5) estimating uncertainty, and (6) data reporting, including use of the R package ‘seacarb’. Participants will have access to SeaFETs, Durafet arrays, and other resources (e.g., R code, LabView VIs) to ensure successful implementation of these instruments at their home institution. The goal of this workshop is to create a user group operating with standardized best practices to enhance data quality and reporting.

Individuals who wish to attend should send an email to Dr. Kapsenberg (lydia.kapsenberg(at)obs-vlfr.fr) by 11 August 2017 with a brief description of his or her background on this topic and reason for attending. The workshop is limited to 20 participants on first-come-first-serve basis with priority to one representative per institution. Participation will be confirmed via email by 15 August 2017.

Travel expenses and housing will need to be covered by the participants. The workshop will start at 13:00 on Monday (11 September 2017) and end at 16:00 on Tuesday (12 September 2017), to facilitate same-day travel and minimize housing costs.

The workshop is made possible by a U.S. National Science Foundation Ocean Sciences postdoctoral fellowship in collaboration with Prof. Todd Martz from Scripps Institution of Oceanography and the University of Pierre and Marie Curie Paris. For more information, please contact Dr. Kapsenberg.
