WP 4.1 / D4.1The role of gliders in sustained
observations of the ocean
David Smeed (NOC), presented by Jan Kaiser (UEA)
Final General Assembly – Paris, France – September 19, 2014
Sustained ocean observations
• Motivation• Opportunities and challenges for glider
technology• Examples of sustained observations from
gliders• Conclusions
Final General Assembly – Paris, France – September 19, 2014
Motivation
• CLIVAR program: "Maintain over many decades a sustained ocean observing system capable of detecting and documenting global climate change".
• Long-term perspective for climate research• Long-term monitoring is a fundamental
requirement of the European Union (EU) Marine Strategy Framework Directive (MSFD).
Final General Assembly – Paris, France – September 19, 2014
Sustained sub-surface observations
• Repeat sections, either hydrographic sections by research vessels; XBT sections from vessels of opportunity
• Fixed observatory sites – e.g. hydrographic data at Ocean Weather Ship Station (OWS) Mike in the Norwegian Sea since 1948.
• ARGO network of profiling floats

The ARGO programme
Final General Assembly – Paris, France – September 19, 2014
Opportunities and challenges for glider technology
• growing range of oceanographic sensors • Argo profiling floats cannot sample at specific
locations and little data is obtained on the continental slope
• GROOM partners have tested the capability of gliders to make sustained observations.
Final General Assembly – Paris, France – September 19, 2014
• To provide more frequent sampling than is possible with available ship-time or budget.
• To obtain data with higher spatial resolution.
• To obtain data in real-time for data assimilation and for increased data security.
Why use gliders?
Final General Assembly – Paris, France – September 19, 2014
• 11 projects run by GROOM partners in which gliders were trialed or are regularly used for sustained observations.
• In some cases, glider have replaced other platforms or enabled new programs to start
• But there are some cases where gliders were found to not yet be suitable or cost effective.
Sustained observations by gliders in GROOM
Final General Assembly – Paris, France – September 19, 2014
• Advantages– more frequent sampling per ship-time and budget– higher spatial resolution.– real-time data for assimilation and more data
security• Disadvantages
– navigation in strong currents difficult– reliability– additional resources required– risks of collision with vessels
Conclusions from GROOM missions
Final General Assembly – Paris, France – September 19, 2014
• ships observations were biased to the summer months (see plot below)
• now: 3 years of quasi-continuous glider observations
Example 1: The Balearic Channels in the western Mediterranean
Final General Assembly – Paris, France – September 19, 2014
• RAPID requires continuous data, and the reliability of gliders was not sufficient to replace the moorings.
• Gliders effective for measuring near surface / very difficult with moored instruments
Example 2: RAPID project at 26° N
Final General Assembly – Paris, France – September 19, 2014
The use of gliders is most successful when• gliders can completely replace other platforms
(e.g. Balearic Channel)• there is easy access to deployment and
recovery sites close to shore (e.g. Balearic Channel)
• it is only required to sample the upper 1000 m (e.g. shallow thermocline in the Mediterranean Sea; Ruiz et al., 2012).
Conclusions 1
Final General Assembly – Paris, France – September 19, 2014
Types of sustained observation for which gliders are particularly well suited:• real-time data thanks to glider data
telemetry • continental slope where Argo data are rare• near surface where moored instruments
are difficult to use
Conclusions 2
Final General Assembly – Paris, France – September 19, 2014
Future needs include• improved reliability (cf. APEX floats)• increased depth capability (but: implies
reduced repeat sampling frequency)• increased endurance to make larger parts
of the ocean accessible from individual glider ports

Task 4.2: Fleet missions
responsible person: Alberto Alvarez contributors: NURC, UPMC, OGS, IFM-GEOMAR, CNRS, CSIC
• plan, execute and review trials of missions involving a fleet of at least 3 gliders simultaneously.
• define optimal sampling strategies (for example, glider swarms, how can we sample an eddy more efficiently with 2 gliders, 3 gliders or more).
• test auto piloting programmes, adaptive sampling strategies and OSSEs

• trial new sensors on gliders (linked with WP5) to assess their capability (for example, carbon cycle, turbulence, nutrients).
• compare different design strategies for gliders with Argo floats, moorings and ship-board studies
• compare sensor behaviours for each technique compared. • test synergies between gliders and other components of the
global ocean and coastal observing systems. • demonstrate the in-field calibration protocols developed in WP5.2
(sensor payloads).
