Arctic Regional Hydrographic Arctic Regional Hydrographic CommissionCommission

• Highlights since IRCC-6 (2014)– Responded to request of PAME (Arctic Council) to assess

chart adequacy in the Arctic and report at PAME-II 2014 – Progressed the concept of an Arctic Voyage Planning

Guide for anticipated launching in 2015 after ARHC-5 discussion

– Conducted special inter-sessional meeting of ARHC-5 in October during the EIHC

– Finland, Iceland and the IHB continue as ARHC Associate Members

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.

1. Determine Confidence of Hydrographic Holdings.

2. Define Depth Bands based on Seafloor Complexity.

Low Concern

Complex: 0-100m, 100-200m, 200+ m

Simple: 0-20m 20-50m > 50m

Complex: 0-100m 100-200m > 200m

3. Intersect Areas of Confidence with Depth Areas to determine

Potential Areas of Concern.

Med. Concern

High Concern

Highest Concern

4. Extract “High Risk” Vessel Traffic Tracklines and Intersect with Potential Areas of Concern.

5. Compute Area Geometry of Potential Areas of Concern and Linear Distance Traversed by

Vessel Traffic within each Area type.

Satellite-Observed Vessel Traffic Patterns(e.g. Higher Confidence

and/or Deeper Depths)

(e.g. Lower Confidence and/or Shallower Depths)

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

Next Steps

– 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
