IHO Standards for Hydrographic Surveys, Edition 6.0.0 September 2020.
This publication aims to provide a set of standards for hydrographic surveys primarily used to compile navigational charts essential for the safety of navigation, knowledge and the protection of the marine environment. It specifies the minimum standards to be achieved based on the intended use. Where and when necessary, hydrographic offices or organisations are encouraged to define more stringent or specific requirements as national or regional realisations of the standard. This publication does not contain procedures for setting up equipment, conducting the survey, or for processing the resultant data. IHO Publication C-13, Manual on Hydrography, should be consulted for information on those topics (downloadable from the IHO homepage: www.iho.int).
In this edition, a new, more stringent Exclusive Order has been introduced. The use of Exclusive Order should be limited to areas with exceptional conditions and specific requirements. The other orders for safety of navigation surveys have kept the same names, but their interpretation has changed from the previous edition due to the introduction of the bathymetric coverage concept. Special Order now explicitly requires full bathymetric coverage. Furthermore, the orders have been divided into requirements above and below the vertical datum.
This edition aims to encourage the use of S-44 for purposes beyond the safety of navigation. It introduces the concept of a Matrix of parameters and data types to define realisations of survey standards and specifications. This Matrix alone is not a standard. It should be considered as a reference to specifying dedicated surveys, as appropriate, and to provide a tool for a broader classification of surveys. It is, by design, expandable and can evolve in future S-44 versions. Annex A provides guidance on how the Matrix can be used for specification and classification of surveys.
S-44 vocabulary has been revised in order to more closely align with references typically used in metrology (e.g. Guide to the expression of uncertainty in measurement). Horizontal positioning standards for aids to navigation have been revised and standards on their vertical positioning have been added. Emphasis has been placed upon the main components of hydrographic surveys while being technology independent.
While the hydrographic surveyor may have some flexibility on how to conduct survey operations, it remains the decision of the responsible authority on whether the standard has been achieved. Furthermore, the surveyor is an essential component of the survey process and must possess sufficient knowledge and experience to be able to operate the system to the required standard. Measuring this can be difficult, although surveying qualifications may be a basis in making this assessment. Available education in this field is (amongst others) Category A and/or B educational programme formed by International Board on Standards of Competence for Hydrographic Surveyors and Nautical Cartographers (IBSC), International Hydrographic Organization (IHO), International Federation of Surveyors (FIG), International Cartographic Association (ICA).
The information contained in annexes B, C, and D provide some guidance on quality control, data processing, and considerations for gridded bathymetry. These Annexes are not an integral part of the S-44 Standards and will be removed when the information therein is fully incorporated into IHO Publication C-13, Manual on Hydrography.
Note: The publication of this new edition of the standard does not invalidate surveys, or the safety of navigation products based on surveys conducted in accordance with previous editions.

Best practices related to mooring set-up. Presented at: Workshop on training for less experienced users of hardware 15th September 2015, Trieste, Italy.
Bensi, Manuel; Siena, Giuseppe
Approaching an oceanographic mooring Principles of “Best Practices” in all phases of the system (predeployment test, maintenance, calibration etc.) should be followed.
They cover the entire infrastructural chain of data acquisition from
sensor (performance, robustness, accuracy, etc.) to supporting
system (cabling, electric and electronic components, etc.). The
user needs to take into account:
• Scientific aim (geographic location, physical and
biogeochemical properties in the region, etc.)
• Mooring Design
• Chose of hardware
• Technical and scientific staff
• Logistics
• Costs
• Risks

The WMO Voluntary Observing Ships' Scheme.
The international scheme under which ships plying the various oceans and seas of the world are
recruited for taking and transmitting meteorological observations is known as the WMO Voluntary
Observing Ships’ Scheme. The forerunner of the scheme dates back to 1853, the year in which
delegates of 10 maritime countries came together at a conference in Brussels, on the initiative of
Lieutenant Matthew F. Maury, then director of the U.S. Navy Hydrographic Office, to discuss the
establishment of a uniform system for the collection of meteorological and oceanographic data
from the oceans and their use for the benefit of shipping. In the twentieth century, the system was
recognized in the
International Convention for the Safety of Life at Sea (SOLAS)as amended,
which specifies in Regulation 5 of Chapter V — Safety of navigation — that ‘the Contracting
Governments undertake to encourage the collection of meteorological data by ships at sea and to
arrange for their examination, dissemination and exchange in the manner most suitable for the
purpose of aiding navigation’.

Many Arctic and Baltic nations maintain Ice Services and issue ice charts on a regular basis when
marine activities are occurring in the vicinity of
sea ice and icebergs. These ice charts are used on ships as an aid to navigation in ice infested
waters. Electronic Navigation Charts (ENC) and
Electronic Chart Display and Information Systems
(ECDIS) are becoming widely available on ships
navigating in icy waters and it is necessary to provide ice data in a form that can be used in these systems.
The ENC Ice Objects Catalogue has developed slowly since the mid-1990’s. Initially, several ad-hoc workshops were held involving experts from national ice services, national hydrographic
organizations and private companies involved in the manufacture of electronic charts and display systems.

VOS Quick Reference Guide - Port Meteorological Officers. [Web document]
JCOMM Ship Observations Team
The purpose of this "Quick Reference Guide" is to:
Help newly appointed personnel become familiar with the functions of a PMO;
Reacquaint experienced personnel with these functions; and
Promote the resources available to fulfil these functions.
Note: This guide is presented in point form and should be used in conjunction with the Quick Reference Guide for VOS Program Managers, as the separation of responsibilities and tasks expressed here might not be representative of all countries. The two guides when combined should cover the basic requirements of operating and maintaining a national VOS Program. Many of the functions of the PMO described in this guide are summarised in the VOS Work Flow Diagram.

JCOMM Expert Team on Sea Ice
A number of northern nations, particularly, Canada, Denmark, Germany, Norway, Russian Federation, the United States, and those bordering on the Baltic Sea, maintain Ice Services (for a complete list of national ice services refer to the WMO publication No.574 "Sea Ice Information Services in the World", 3rd edition, 2006), and issue ice charts on a regular basis during winter months. These ice charts are used on ships as an aid to navigation in ice infested waters, and as ECDIS becomes more widely available on ships navigating these northern waters, it will be important to provide ice data in a form that can be used in those systems.

XBT/XCTD standard test procedures for reliability and performance tests of expendable probes at sea. Revised draft.
Sy, Alexander; Wright, Darren
The best way to assure a quality XBT or XCTD is to implement a standard set of procedures for testing the probes. This document proposes a three step process for insuring XBT/XCTD quality: 1. Start with a set of specifications that must be adhered to, by either laboratory testing or documentation from the manufacturer, before proceeding onto the field evaluations. 2. Next is a standard reliability testing procedure under normal ship of opportunity conditions, i.e. on a vessel underway. 3. Finally and most important is a side-by-side comparison with a cable lowered high precision CTD as a field reference.
