ARHC’s Methodology to Answering PAME(Ref.: IRCC7-11G A Risk-based Methodology of Assessing the Adequacy of Charting Products in the Arctic Region: Identifying the Survey Priorities of the Future)
1. Assess confidence of the present hydrographic holdings (Age of data, Type of coverage, etc.).
2. Divide ocean into general depth categories based (shallow, mid-depth, deep) factoring in seafloor complexity .
Ex: across a broad flat shelf, 30m could be considered “deep”; whereas, in areas with the potential for sharp, sudden rises in the seafloor, 50m could be considered “shallow”)
3. Intersect confidence (#1) with depth bands (#2) to develop potential areas of concern.Ex: Higher conf. hydro plus deeper depths = Lower concernEx: Lower conf. hydro plus shallower depths = Higher concern
4. Assess historic traffic patterns as they relate to the areas of concern (#3).5. Generate maps and statistics which can guide decision-making processes.Ex: Hydrographic organizations can determine survey prioritiesEx: Coast Guards can determine where to stage equipment for potential rescue or spill response events.
Higher Risk Vessels:•Tankers•Cargo and Tugs•Passenger Vessels
Output:•Frequency of Vessels transiting within Areas of Higher/Lower Concern…•… thus quantifying whether region is adequately charted.
Lowest Concern
• Key messages to PAME Arctic Council– Hydrography matters
• Critical for the protection of the Arctic marine environment through safe navigation and better science which underpins:– Safe maritime commerce– Resilient coastal communities– Ecosystem management (e.g. sensitive areas)
– ARHC is the expert group actively conducting hydrography-related science and analysis in the Arctic• Independent, inter-governmental, and inclusive• Committed to long-term partnerships• This work is just beginning
– August: WMU/WMO ShipArc 2015 Conference (Malmö, Sweden)– Denmark Geodata Agency will present on behalf of ARHC
– September: PAME-II in September 2015 (Tromso, Norway) • PAME requests the Secretariat to invite the Arctic Regional Hydrographic
Commission (ARHC) to submit and update progress on the status of Arctic hydrography and charting, as well as any developments with respect to Arctic Voyage Planning Guides.
• The Chair of OTWG is currently seeking additional MS contributions to the Hydrography and charting assessment and methodology
– Ongoing: Complete ARHC-4 actions and consider more collaborative regional effort to respond on such topics as C-55 and ARHC input to the IHO work program, etc…
– Pending: ARHC-5 (Tentative November 2015)
– ARHC-5: AVPG review and hoped for release with help of IHO portal
