Tide Gauges Map

http://www.prsn.uprm.edu/English/EstacionesV2/tidegauges.php

• This map shows all gauges stations monitored in real-time at the PRSN.

• The map is divided in 3 sections; Caribbean, Northeastern Caribbean and Puerto Rico

• Colors of the triangle represents the latency of the station over that time interval. Example: a green triangle means no (or less than 10 min) gaps, a red triangle means no data.

• The first part shows the station details, including location on Google map and a picture of the station.

• The second part displays the data on a plot view. The data shown represents the last day. To search for more data click “Perform another search”.

• The Blog contains a station log and other records.

Latency – tide Quality & Availability

Qtide is used to measure the quality & availability of a data set generated periodically by the gauges stations.

Qtide – Form

• Using this form, you select the station and the date range of your search.

Qtide – Table

• The first table shows the degree of completeness. • The second table shows the gap list.

Qtide – Graph

• This graph shows gaps from each sensor of the station selected. Red means no data.

GLOSS - The Global Sea Level Observing System

Establishment of high quality global and regional sea level

networks for application to climate, oceanographic and

coastal sea level research and monitoring.

Coordinated by the Intergovernmental Oceanographic

Commission (IOC)

Major contributor to IOC’s Global Ocean Observing System

(GOOS)

Organizes and supports training courses, including the

Caribbean and publication of manuals for operators and sea

level reports for GLOSS stations by UHSLC and UK Proudman

Sea Level Center

COCONet Project NSF/UNAVCO/2.5 M US$ To be able to get better

geodetic control and address the issue of ground displacement vs sea level changes over short time term (earthquake/tsunami) and long term (sea level), efforts are being made to collocate some of the COCOnet GPS stations within 1 km of existing or proposed sea level stations.

The final COCONet siting plan. Green dots represent new (50) or refurbished stations (15), red dots represent existing stations (61), and the blue triangle represents one alternate site on Sombrero Island. Large green dots represent the seven completed COCONet stations to date.

CTWC“Providing regional service,

strengthening local capabilities…”

• NOAA NWS established in February 1, 2010 the Caribbean Tsunami Warning Program, jointly located at the Puerto Rico Seismic Network at the University of Puerto Rico at Mayagüez as a 1rst step of the U.S. towards the establishment of a Caribbean Tsunami Warning Centre.

• Endorsed by UNESCO/IOC/CARIBE EWS

• Funds are yet to be identified for full implementation of Center

CTWC“Providing regional service,

strengthening local capabilities…”

• Currently supports and monitors all sea level stations in the Caribbean using Tide Tool.

• Co-Organizer of June 2011 CARIBE EWS sea level network operator workshop in Mexico

• Received special funding of $80,000 to develop tools for integration of sea level data into Caribbean and Western Atlantic Hydromet Offices and Tsunami Warning Focal Points

• PRSN with the University of Hawaii and funding from NWS is installing and providing maintenance thru at least 2013 for 10 Tide Gauges installations in the Caribbean (only sea level, no met component).• 2 Dominican Republic• 2 Colombia• Panama• Limon• Grand Turks• Curacao• Grenada• Dominica

• PRSN with UNESCO and funding from Brazil and Saint Kitts/Nevis is installing 5 Tide Gauges in Caribbean.• Nicaragua• Guatemala• Cayman• Saint Vincent• Saint Kitts• Haiti

• PRSN with ONAMET with NWS funding is installing a station.• Barahona, Dominican Republic

• Predicted tides for stations• Improving the Tsunami monitoring system.

PRSN work in progress

Issues with Caribbean Sea Level Stations

• Broaden the user base, currently the sea level data is ingested by the TWC, but is mostly underutilized for other climate/hydromet/shipping applications.

• Additional training for sea level network operators-next workshop for June 2012 in Mexico (UNESCO/UNAM/NWS)

• Explore alternatives for robust real time high rate transmission, 1minute.

• Need for QC for many of the stations

• Need to determine the predicted tides for many stations

• Need for a Caribbean Sea Level Data Center as a repository and for data QC/Analysis

• Publication on Caribbean sea level data
