Request for Proposals for a lead Hydrographer for the Maine Coastal Program’s Mapping Initiative

Request for Proposals for a lead Hydrographer for the Maine Coastal Program’s Mapping Initiative

Hydrographer Services for the Maine Coastal Mapping Initiative

The State of Maine is seeking proposals for services as the lead hydrographer for the Maine Coastal Program’s Mapping Initiative.

A copy of the RFP, as well as the Question & Answer Summary and all amendments related to this RFP, can be obtained at the following website:

Proposals must be submitted to the State of Maine Division of Procurement Services, located at the Burton M. Cross Office Building, 111 Sewall Street – 4th Floor, Augusta, ME 04330.  Proposals must be submitted by 4:00 pm, local time, on March 6, 2018, when they will be opened.  Proposals not received at the Division of Procurement Services’ aforementioned address by the aforementioned deadline will not be considered for contract award.

The Maine Coastal Program’s Mapping Initiative acquires seafloor and marine habitat information including bathymetry and backscatter data, sediment information, fauna type and abundance, and water column data. The data contribute to numerous ongoing efforts including identification and characterization of potential sand and gravel resources that may be used for beach replenishment, assessment of nearshore sand movement over time to inform beach nourishment projects, investigations of cable areas and other State Submerged Lands Programs interest areas, and marine habitat modeling. This project also provides new data that are incorporated into National Oceanic and Atmospheric Administration (NOAA) nautical charts.

GSM Fall 2017 Meeting

GSM Fall Meeting, November 17, Augusta Civic Center  <See program>


Our Fall Meeting this year will feature presentations from people who work with Maine’s mineral resources from a variety of perspectives.  There will be presentations by economic geologists, exploration geologists, aggregate producers, environmental regulators, and a researcher into public perceptions about mining in Maine.  We will hear about the new metallic mining rules that were finally adopted this month on November 2.  A distinguished panel including Maine legislators who participated in the process will be on hand for questions and discussion.


We will begin with the annual business meeting at 1:00 pm in the Washington and York Rooms on the second floor of the Civic Center.  Please join us for an enjoyable afternoon with colleagues.

2018 Geologic rafting trip through the Grand Canyon

Again as in the past 10 years, Alison Jones and Fred Beck will be leading an 8-day rafting trip of about 188 miles through the Grand Canyon.   Many GSM members have made this trip in the past, some going twice.  The trip begins at Lee’s Ferry, Arizona, and ends at Whitmore Wash followed by a short helicopter ride to an airstrip at the Bar 10 Ranch on the North Rim.  The dates are August 6-13, 2018.  From there you will be flown to Las Vegas or Lee’s Ferry.

The emphasis of these trips is of course about the geology, from Precambrian through the Permian as well as an abundance of more recent events including volcanism, breccia pipe formation, spring deposited travertine, debris flows and much more.   At least two modest hiking trips are made each day into slot canyons or other side canyons and tributaries to visit waterfalls, fossils, archaeological sites and just to get out and stretch our limbs or swim in clear warm water.  Some choose not to do some of the side trips and just relax or read near the rafts while others go adventuring.

There are usually as many non-geologists on these trips as geologists and they get as much out of the trip as the geologists; a perfect geologic classroom.  We have often had teenagers on these trips and that has added to the fun.

The outfitter we use is Hatch River Expeditions, one of the most experienced companies licensed to operate in the Grand Canyon.  There will be two 34-foot inflatable boats powered by 30 HP outboards.  No paddling or rowing on this trip.  Each raft accommodates 16 people as well as all our gear, food, etc.   All meals are prepared by the Hatch guides and Hatch also provides all tents, cots, bedding, etc.

If you are interested in more details, contact Fred Beck at or Alison Jones at  We anticipate that we will have a full complement of travelers by the end of this September so an early commitment is advised.
