Explanatory Notes


Geographical positions  refer directly to the graduations of the largest scale Canadian Hydrographic Service chart (unless otherwise indicated).

Bearings refer to the true compass and are measured clockwise from 000° (North) clockwise to 359°; those relating to lights are from seaward.

Visibility  of lights is that in clear weather.

Depths  - The units used for soundings (metres, fathoms or feet) are stated in the title of each chart.

Elevations are normally given above Higher High Water, Large Tide (unless otherwise indicated).

EXPLANATION OF TEMPORARY AND PRELIMINARY NOTICES TO MARINERS

Certain Notices to Mariners appearing in the monthly editions have a (T) or (P) appended to the regular number. These letters indicate that the information contained in the notice is of a temporary or preliminary nature, respectively.

TEMPORARY (T) NOTICES

If a temporary change in conditions affecting navigation exists and if the change will be effective for a period of over three months, a temporary (T) notice will be published. Temporary changes which are effective for periods of less than three months will not normally be published (unless it is of exceptional interest). Otherwise, information will be promulgated as a Navigational Warning (NAVWARN) by the Canadian Coast Guard Marine Communications and Traffic Services (MCTS) Centre(s) in the affected area. (T) notices will be cancelled as necessary.

Please note that (T) notices with an end date will be automatically cancelled once the end date has passed. In the event of a change to these notices, a new Notice to Mariners will be issued.

PRELIMINARY (P) NOTICES

a. When important changes affecting navigation are to take place in the near future, a Notice to Mariners describing the change will be published, so that mariners will have advance information on the change. Such notices will be designated (P).

b. When a change in conditions affecting navigation has taken place but full information is not available, a preliminary (P) notice giving available information will be published. This notice will be followed by a regular notice when complete information becomes available. The regular notice will cancel the (P) notice.

c. When a change has taken place which is too complex to describe in a written notice, a (P) notice giving general information will be published. This notice will explain that follow up action will be taken to update charts by publishing patch corrections, new editions or new charts.

Please note that following the expiry of the 90-day comment or objection period, (P) notices describing proposed changes or intention to discontinue will be automatically cancelled. In the event of a change to these notices, a new Notice to Mariners will be issued.

ACTION REQUIRED ON RECEIPT OF (T) & (P) NOTICES

It is not customary to make permanent corrections to charts and publications from (T) & (P) notices. On receipt of such notices, the information they contain should be noted in pencil on the affected charts and/or publications.

CAUTION

Mariners are reminded that charts and publications are not corrected from (T) & (P) notices when purchased from suppliers. For the list of charts affected by (T) & (P) notices, please refer to the index on page ii of this publication.

*819(T)/16AUTOMATIC IDENTIFICATION SYSTEM (AIS)
AIS Application-Specific Messages (ASM) and AIS AtoN

Mariners are advised that the Canadian Coast Guard will perform a test of AIS Application-Specific Messages (AIS- ASM) on the Pacific Coast from the Sand Heads meteorological/hydrological station: 49°06’21’’N 123°18’12’’W, and may extend this testing to other stations in the coming months. The test will start at the end of August and consist of broadcasting meteorological/hydrological (MET/HYDRO) data through AIS binary “Message 8”.

Although AIS was originally developed as a means for positive identification and tracking of ships, it includes functionalities to transmit binary messages such as MET/HYDRO information and other types of data. These additional functionalities of AIS may be useful to mariners to assist in onboard voyage planning.

Ships need to be equipped with a proper Class “A” AIS device for the accurate onboard display of AIS message. The IMO mandatory carriage requirement for the Class “A” AIS displayFootnote 1is the Minimum Keyboard Display (MKD) which displays the binary data in an alphanumeric form. However, as there is no current requirement for the MKD to be capable of decoding all AIS binary messages, the display and use of the ASM information may require additional hardware and/or softwareFootnote 2 .

AIS Aids to Navigation (AtoN)

The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) defines an AtoN as:
‘a device or system external to vessels that is designed and operated to enhance the safe and efficient navigation of vessels and/or vessel traffic’.Footnote 3

The primary purpose of an AIS AtoN Station is to promote and enhance safety and efficiency of navigation by one or more of the following:
  • Providing a positive and all-weather means of identification;
  • Complementing existing services (e.g. RACONS) from AtoN;
  • Transmitting accurate positions of floating AtoN;
  • Indicating if a floating AtoN is off position (monitoring the status of an AtoN);
  • Marking or delineating tracks, routes, areas, and limits;
  • Marking offshore structures;
  • Enable timely marking of new hazards (fixed or dynamic) using Virtual AIS AtoN.


The use of AIS within the marine aids to navigation service is accomplished by the broadcasting of the aids to navigation report message “Message 21”.

An AIS AtoN can be implemented in three ways, Real, Synthetic, and Virtual.
  1. Physical/real AIS AtoN: An AIS device which is physically located on the AtoN and transmits “Message 21”.
  2. Synthetic AIS AtoN: There are 2 types of Synthetic AIS AtoN – Monitored and Predicted.
    1. Monitored: A “Message 21” is transmitted from a nearby AIS base station. The AtoN physically exists but there is no AIS device on it. A communication link is installed on the AtoN to allow the monitoring of its status.
    2. Predicted: A “Message 21” is transmitted from a nearby AIS base station. The AtoN physically exists but there is neither an AIS device on it nor a communication link. Status and position of the AtoN cannot be monitored.
  3. Virtual AIS AtoN: A “Message 21” is transmitted from a nearby AIS base station for an AtoN that does not physically exist. The “Message 21” will clearly identify this as a virtual AIS AtoN.
Displays and Symbology

As the AIS information available to mariners will be dependent on their display system, not all transmitted information may be displayed. Mariners are encouraged to install systems that provide AIS overlay on either ECDIS or Radar, or both.

Of those vessels that are AIS equipped the various displays available can range from no display on some Class B units, through to the mandatory Class A MKD, and to a full ECDIS or Radar overlay. In the absence of an ECDIS or Radar overlay, mariners will not be able to fully utilize the AIS AtoN functionality. Also note that there is a variance in the information that can be displayed on ECDIS or Radar equipment by the different AIS manufacturers.

The symbology that may be displayed on nautical charts, display systems and the MKD is summarised below.

Nautical Charts On nautical charts AIS AtoN are indicated by a magenta circle surrounding the existing AtoN symbol and an adjacent legend stating AIS. The font will be straight for fixed AtoN and italic for floating AtoN.
Avis au Navigateurs - système d'indentification automatique A physical AIS AtoN provided as an overlay on ECDIS, Radar or other display systems are indicated by a diamond shape with crossed lines at the reported position of the AtoN. A physical AIS AtoN that is off position will use the same symbol but in red. A virtual AIS AtoN is indicated by a dotted line diamond shape with the crossed lines at the reported position.

Minimum Keyboard Display
The mandatory MKD is only required to display data in alphanumeric form. Some MKD are units supplemented by a small graphical display. Exact presentation will vary but this layout below would be typical of MKD displays.
