ce Navigation in Canadian Waters

 

 

 

Ice Navigation in Canadian Waters 

is published by the Canadian Coast Guard in collaboration with Transport Canada Marine Safety, the Canadian Ice Service of Environment Canada and the Canadian Hydrographic Service of Fisheries and Oceans Canada. The publication is intended to assist ships operating in ice in all Canadian waters, including the Arctic. This document will provide Masters and watchkeeping crew of vessels transiting Canadian ice-covered waters with the necessary understanding of the regulations, shipping support services, hazards and navigation techniques in ice.

Chapter 1, Icebreaking and Shipping Support Services, pertains to operational considerations, such as communications and reporting requirements as well as ice advisories and icebreaker support within Canadian waters.

Chapter 2, Regulations and Guidelines provides a summary of information on regulations and guidelines for

Multibeam Sonar to Detect Subsea Leakage

MBES technology has wide applicability in subsea leakage detection. The technology uses acoustics (sound signals) to build up maps of underwater space. This leaves the underwater environment undisturbed, which is particularly important in situations of hydrocarbon leakage. The Norbit Winghead, launched in mid-2020, is a unique curved-array ultra-high-resolution bathymetry sonar system utilizing the latest in analogue and digital signal processing.

The Norbit Winghead is versatile, easy to use and optimized for rapid mobilization on any platform. It offers a 0.5° x 0.9° beam width at 400kHz and a HD beamformer providing 1,024 beams per ping. The system’s low power consumption means that it can be battery operated. It provides a simple ethernet interface and signal processing capabilities, including roll stabilization, water column and backscatter

Innovations and Partnerships in Ocean Mapping: What More Could We Achieve?

Most people working in hydrography know very well that better ocean data can be used to inform a variety of decisions, from storm preparedness to helping develop the blue economy. But could we do more in terms of fostering innovations or partnerships within our network? Could we do more with our existing partners?

These questions are prompted by a review of some of the work being done within the IHO. We initiated this year for example a trial project with CSIRO in Australia, funded by the Australian Hydrographic Office, to see whether accurate and reliable depth data can be extracted from Argo recordings. Argo is an international programme that collects information on the ocean using a

NOAA Formally Joins International Effort to Map Ocean Floor

 NOAA Administrator Rick Spinrad has signed a memorandum of understanding in conjunction with the United Nations Ocean Conference that formalizes U.S. participation in Seabed 2030. The memorandum also describes best practices and protocols for this type of data collection, which will help build positive collaboration between all involved countries and partners. As of 2022, 23.4% of the ocean is mapped, reflecting an increase of 10.1 million square kilometres (almost 3.9 million square miles) of new bathymetric data from 2021.

The new number represents contributions from a wide and diverse group of stakeholders, including various nations, government agencies, private companies, philanthropic partners and academic institutions.
