Biography

Overview

I'm the technical lead of the Permanent Service for Mean Sea Level (PSMSL), which since 1933 has provided the global dataset of mean sea level measured at tide gauges. We work with many operators of tide gauges from around the world to provide data to whoever wants to use it.

As the technical lead, I'm responsible for the PSMSL website, its internal data storage systems, and the software we use to update both. I also provide advice to providers and users of tide gauges on issues around the collection, quality control, storage, distribution, and analysis of tide gauge data.

I also maintain the PSMSL's GNSS-IR portal, providing sea level data using GNSS interferometric reflectometry.

Other responsibilities

Best practice in sea level measurement and quality control
Best practice in tidal analysis
Recovery of historical tide gauge data
Quality control of UK South Atlantic data

Committee Memberships

GLOSS (Global Sea Level Observing System) steering committee

EuroGOOS data management, exchange, and quality control working group (DATAMEQ)

Roles Provided

Technical lead of the Permanent Service for Mean Sea Level (PSMSL)
