Permanent Service for Mean Sea Level (PSMSL) and
some related information
  • Philip L. Woodworth
  • Svetlana Jevrejeva
  • Simon Holgate
  • Permanent Service for Mean Sea Level
  • Proudman Oceanographic Laboratory, U.K.

Change of Our Address in December
  • PSMSL and POL are moving to the campus of
    Liverpool University
  • Proudman Oceanographic Laboratory
  • Joseph Proudman Building
  • 6 Brownlow Street
  • Liverpool L3 5DA
  • Emails and web stay the same

  • Some Changes
  • UK Perspective
  • Our Research Council and Government Ministry
    (DEFRA) have established a UK National Tidal
    Sea Level Facility (POL, BODC, other
    DEFRA-related work e.g. by Nottingham University)
  • All UK data (1990 on so far) are now freely
    available on the web (whether a GLOSS tide gauge
    or any other). Older historical data will be
    added in due course
  • Relevant data will be copied to ESEAS, GLOSS etc.
    completely freely
  • http//www.pol.ac.uk/ntslf/

  • REMINDER ABOUT HIGHER FREQUENCY DATA
  • Fast High-Frequency Data
  • UHSLC IS THE GLOSS FAST DATA CENTRE see Mark
    Merrifield at this conference
  • Delayed Mode High-Frequency Data
  • Send HF Delayed Mode data (as required by GLOSS
    Implementation Plan) to either UHSLC or PSMSL
  • In practice, BODC will perform this GLOSS
    Archiving Centre for PSMSL. Send data to Lesley
    Rickards.
  • UHSLC and BODC will undertake similar roles for
    sea level data for CLIVAR

  • REMINDER ABOUT MSL DATA TO PSMSL
  • Mean Sea Level Data
  • Please continue to send MSL data to the PSMSL -
    see Svetlana Jevrejeva at this conference
  • GLOSS Status measured by data receipts at PSMSL
    improved slightly during 2003 but we still need
    to give reminders to a number of authorities.

PLEASE TAKE A GOOD LOOK WHY IS YOUR COUNTRY NOT
RED? I) Data not delivered to the PSMSL because
we got out of the habit of sending and receiving
MSL data ? See Svetlana Jevrejeva at this
conference II) Data are not released for some
reason. MSL data have little commercial or
national security value ? Long list of IOC
resolutions on this subject. III) No (or
inadequate) gauges exist. IV) Some other
blockage
16
  • Examples
  • South Africa
  • II) New Zealand
  • III) Certain African States, Yemen, Russian
    Arctic, Pakistan, Indonesia, Brazil
  • IV) CPACC countries
  • III and IV are related to why we are having this
    technical workshop.

Summary of GLOSS Data Streams FAST H-F data to
GLOSS Fast Centre at UHSLC DELAYED MODE H-F
data to either PSMSL/BODC or UHSLC MSL data
(and associated datum information) to PSMSL GPS
data TIGA Centre at Potsdam But PSMSL remains
grateful to receive MSL data from both GLOSS and
non-GLOSS stations.
