We will be staying at the Sheraton Portsmouth Harborside Hotel in Portsmouth, New Hampshire, USA where the GEBCO GCC meetings will be taking place on 4-8 November.

The Arctic-Antarctic-North Pacific Mapping meeting will be either at the Sheraton or at the Center for Coastal and Ocean Mapping at the University of New Hampshire in Durham. This decision will be made later – if the meeting is in Durham, transportation from the Sheraton will be arranged.

Participants are expected to make their own accommodation arrangements but are encouraged to stay at the Sheraton Portsmouth Harborside Hotel for convenience. This hotel offers special rates for the delegates if they book before 3 October 2019 through this link.

If the participant wants to stay in said hotel but has missed the cut-off date for booking, please let Renee Blinn ( ) know so she can arrange for you to get the discounted rate.

The nearest airport for both international and domestic flights is Boston Logan International Airport.

Below are some transportation options from the airport:

  • C&S Airport Service: door to door (limos, van, etc – can be cost-effective if traveling in groups)
  • C&J Bus Service: (this is what most CCOM faculty use) comfortable coach buses with internet, pick up / drop off at your airport terminal every hour. Tickets and schedules are available online. $24 one way, $48 round trip. NOTE: Uber or taxi is required from the bus station to/from Sheraton – approximately $10 each way
  • Private car rental: round-trip Logan airport/Sheraton: $300 - $400, not including insurance or fuel. NOTE: Sheraton offers discounted parking for conference attendees at $10 per day. All activities are at or within walking distance from the hotel with the exception of the CCOM tour (chartered bus), so a rental car is not needed and is highly discouraged. NOTE: there will be larger than usual traffic delays in and out of Boston during that time period, due to extended bridge work.

If we choose to have the Arctic-Antarctic-North Pacific Mapping meeting at CCOM in Durham, transportation to and from the Sheraton will be arranged.


Winter usually starts to slowly creep in by the end of October. The average temperature in November is a high of 20°C and a low of 10°C with possibilities of rain showers. Participants may check this link for the weather forecast.
