Equipment at Tide Gauge Stations
• Sea Level Sensors
• (sensors will vary by station)
• Wind Direction and
• Temperature and
• Rainfall
• Water Temperature
• Barometric Pressure
Aquatrak sensor
Bubbler Sensor
Deep-Ocean Assessment and Reporting of Tsunamis

Tide Gauges Map
• This map shows all
gauges stations
monitored in realtime at the PRSN.
• The map is divided
in 3 sections;
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

Latency – tide Quality & Availability
Qtide is used to measure
the quality & availability of
a data set generated
periodically by the gauges
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.

Only quality control monitored is data availability, the quality of the
data per se is NOT reviewed
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
 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
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
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
“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
• Funds are yet to be identified for full
implementation of Center
“Providing regional service, strengthening
local capabilities…”
• Currently supports and monitors all sea
level stations in the Caribbean using Tide
• Co-Organizer of June 2011 CARIBE EWS
sea level network operator workshop in
• Received special funding of $80,000 to
develop tools for integration of sea level
data into Caribbean and Western Atlantic

PRSN work in progress
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
• Nicaragua
• Guatemala
• Cayman
• Saint Vincent
• Saint Kitts
• Haiti
PRSN with ONAMET with NWS funding is installing a station.
• Barahona, Dominican Republic

Issues with Caribbean Sea Level
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

Stations Progression (1960-present)
