On Friday, October 20, from 12:00–1:00 pm please join us for the next Spatial Technology Lunch in the Center for Spatial Studies (Phelps Hall 3512). This semi-regular series, hosted by spatial@ucsb, aims to promote discussion and interaction within the university’s spatial technology community. Please RSVP to Crystal Bae (cbae@spatial.ucsb.edu) by Wednesday, October 18. Pizza and drinks will be provided.

Monitoring Ocean Acidification on Your Mobile Device

Aaron Bagnell

Bagnell - Tech Lunch
Abstract: A large percentage of the anthropogenic carbon emitted each year finds its way into the world’s oceans. Following the current trajectory, it is anticipated that the resulting ocean acidification will dramatically alter ocean chemistry later this century. But the effects of this change are expected to be non-uniform in time and space, and certain ecosystems and human communities will likely be more susceptible. This poses a challenge for those monitoring the situation when determining where to utilize finite resources, as data on ocean acidification has been historically sparse. Combining high resolution satellite observations with an artificial neural network allows for a generalized method to address the scarcity of this data by providing global estimates of ocean parameters that are of scientific and public value. With this approach, a database has been assembled that provides daily updates to users via a smartphone app, giving them direct access to ocean acidification parameters at tens of thousands of coastal locations.
