At its first meeting in 2020, SERCOM established the Standing Committee on Marine Meteorological and Oceanographic Services (SC-MMO) for the first intersessional period, with the terms of reference provided below. The SC-MMO is comprised of 19 members from all WMO Regions. Leadership is by the Chair, Mr John Parker (Canada) and 2 Vice-Chairs: Ms. Allison Allen (USA) and Dr Sung-Hyup You (Republic of Korea). Membership includes 3 ex-officio positions representing the interests of key WMO partners: the International Maritime Organization (IMO), the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) of UNESCO. Beyond the confirmed 20 members, experts may be invited to the SC-MMO, as needed, to serve as Observers on the Standing Committee, as determined by the Chair/Vice-Chairs of the Standing Committee in consultation with the President of SERCOM.The Chairs of SC-MMO subsidiary bodies observe in the SC-MMO.

The Chair of SC-MMO holds the position of WMO Services representative to the Joint WMO-IOC Collaboration Board (JCB).


The SC-MMO is a subsidiary body of the Services Commission (SERCOM) and, accordingly, reports to SERCOM on a routine basis. Information on SERCOM is here.

The SC-MMO manages 4 Expert Teams reaching across the broad spectrum of maritime safety services, coastal and emergency response, met ocean requirements and capacity development. It also manages an Advisory Group known as the WWMIWS Sub-Committee, comprised of all METAREA Coordinators. A Task Team has also been established to investigate the cost of marine services, as requested by Congress-18.

The organizational chart for SC-MMO is here.

Any questions pertaining to SC-MMO, its parent or subsidiary bodies can be directed to the WMO Secretariat via email

(a) Develop, for consideration by the Executive Council and Congress, proposals for international standards for methods, procedures, techniques and practices in marine meteorology, oceanographic and coastal services (including services on lakes and inland waterways) including, in particular, the relevant parts of the Technical Regulations, guides and manuals;

(b) Under the general guidance of Congress and the Executive Council, carry out functions – with other bodies as necessary – relating to the planning, implementation and evaluation of the scientific and technical programme activities related to marine and coastal services, of the Organization;

Specifically, this will include:

  • develop and maintain WMO normative material related to marine meteorological, oceanographic and coastal service delivery, as specified in the WMO Technical Regulations
  • develop common marine meteorological, oceanographic and coastal service delivery attributes
  • ensure Members are able to contribute to the met-ocean requirements in updating relevant documentation for the International Maritime Organization (IMO) Global Maritime Distress and Safety System (GMDSS) guidelines
  • assist Members to enhance marine meteorological, oceanographic and coastal service delivery capabilities and enable effective implementation and compliance
  • cooperate and partner with relevant bodies, especially the IMO, the IHO and the JCB, to enhance marine meteorological, oceanographic and coastal service delivery.

(c) Update the definition of competency requirements and Quality Management approaches for marine meteorological, oceanographic and coastal services, including the definition of standards for marine services provision and monitoring of their implementation, and maintain the relevant guidance material;

(d) Review and update user needs and requirements on marine meteorology, oceanographic and coastal services;

Duration and Modalities of Work

Until the next ordinary session of the Services Commission where, if required, the SC-MMO can be re-established at the discretion of the Services Commission.

  • Meetings

Note:  Normally WMO would be expected to convene a face-to-face SC-MMO meeting once every two years at its headquarters in Geneva, Switzerland. Consideration may be given by WMO to convene at an alternative location provided, that it increases efficiency without increasing costs to the Organization, for example, back-to-back with relevant IMO, IHO or IOC meeting(s). Since March 2020, a face to face meeting has not yet been possible due to the Global Pandemic. Until such time as travel restrictions ease, meetings will continue online.

  • Tele/video conference

Note:  Normally the SC-MMO would be expected to convene tele/video conferences on at least a quarterly basis, or whenever is required.

  • Correspondence including email exchanges and other appropriate online interactions
