Surveying the waters of Prince William Sound, Alaska

NOAA Ship Fairweather in College Fiord, Alaska

By Matt Canning and Ensign Carly Robbins, NOAA Ship Fairweather

Sheets of ice stretch for miles and miles. Mountains and peaks reach with jagged arms straight for the heavens. Snowmounds inoffensively deafening visitors in the winter months with a quiet like no other. Glacier walls and their child icebergs bobbing in the deep, cold water at every turn. Wildlife of the sky and sea of every shape and size, from Tufted Puffins and Kittlitz’s Murrelets to harbor seals and orcas – this is Prince William Sound.

Aid to navigation recovery operations with NOAA’s Navigation Response Branch and the U.S. Coast Guard

Flushing Bay Channel Lighted Buoy 3 was struck by a tug and barge in late July, and was reported sunk immediately following the strike. The buoy marks the entrance to a channel frequented by commercial barge traffic, specifically, loaded fuel barges bound for LaGuardia International Airport. The Navigation Response Branch (NRB) was called upon in early August to assist United States Coast Guard (USCG) Sector New York in locating the sunken buoy in Flushing Bay, New York.

Learning the ropes aboard a NOAA hydrographic survey vessel

By Natalie Cook

University of New Hampshire’s Center for Coastal and Ocean Mapping and NOAA are giving undergraduate students the opportunity to participate in seafloor mapping and associated exercises aboard a survey vessel this summer. Natalie Cook, a junior in the Ocean Engineering program, is spending eight weeks aboard NOAA Ship Thomas Jefferson, a 208-foot hydrographic survey vessel, experiencing all aspects of hydrography. Natalie is standing survey watch, processing data, working on survey launches, and serving as an active member of the hydrographic survey team.

Surveying the approaches to the Chesapeake Bay

By Ensign Gabriella McGann

After a busy winter in port, NOAA Ship Thomas Jefferson started the 2021 field season in familiar waters, returning to survey the approaches of the Chesapeake Bay. Towards the end of the 2020 field season, the crew of the Thomas Jefferson spent their first 45-day “COVID-19 bubble” on this project. A bubble is formed when crew quarantine and test for COVID-19 prior to crewing the ship, staying isolated onboard until the end of the 45-day period. This protocol is part of the Office of Marine and Aviation Operations (OMAO) COVID-19 mitigation strategy. In April and May of 2021 Thomas Jefferson spent an additional 28 days surveying an area approximately 40 nautical miles east of Virginia Beach, Virginia.

Surveying in the Strait of Juan de Fuca during a global pandemic

By Ensign Jessie Spruill and Hydrographic Senior Survey Technician Simon Swart, NOAA Ship Fairweather

Last Thanksgiving, the crew of NOAA Ship Fairweather were busy surveying in one of the country’s busiest waterways. A global maritime entryway to the Pacific Northwest, the Strait of Juan de Fuca sees over 8,000 transits of deep-draft container ships, cargo and chemical carriers, oil tankers, and barges coming to and from Puget Sound and Canada. In addition to industrial shipping, the Strait of Juan de Fuca also supports over 200,000 transits of recreational vessels and Washington State Ferries. Located north of the Olympic Peninsula, the Strait forms the northwestern most border between the contiguous U.S. and Canada. On the American side, the region is home to eight million people including 50 First Nation communities with centuries old cultural ties to traditional fishing.

The Interagency Working Group on Ocean and Coastal Mapping announces progress report on mapping U.S. ocean, coastal, and Great Lakes waters

The Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) released the second annual report on the progress made in mapping U.S. ocean, coastal, and Great Lakes waters. The depth, shape, and composition of the seafloor are foundational data elements that we need to understand in order to explore, sustainably develop, conserve, and manage our coastal and offshore ocean resources. The 2020 National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone and the global Seabed 2030 initiative make comprehensive ocean mapping a priority for the coming decade. The Unmapped U.S. Waters report tracks progress toward these important goals.

New hydrographic surveying matching fund announced

Update (2/19/21) – Notes and slides from the January 28, 2021, webinar on the NOAA Coast Survey Matching Fund Opportunity are now available.

NOAA’s Office of Coast Survey recently announced a new pilot program for a Hydrographic Surveying Matching Fund opportunity through a Federal Register Notice. The purpose of this notice is to encourage non-federal entities to partner with NOAA on jointly-funded hydrographic surveying, mapping, and related activities of mutual interest. The pilot program relates directly to Coast Survey’s Ocean Mapping Plan and a goal to expand U.S. EEZ mapping by also expanding use of Coast Survey’s hydrographic services contract vehicle.

As the 2020 Atlantic hurricane season came to a close on November 30, NOAA’s Office of Coast Survey tallied a few numbers to see what the combined response effort of the navigation response teams, NOAA Ship Thomas Jefferson, and hydrographic survey contractor David Evans & Associates, Inc., looked like.

NOAA Ship Thomas Jefferson returns to survey approaches to Chesapeake Bay during the 2020 field season

By Hydrographic Assistant Survey Technician Sophia Tigges

For the first portion of the 2020 field season, NOAA Ship Thomas Jefferson surveyed approaches to Chesapeake Bay. Thomas Jefferson’s 2020 field season consisted of two 45-day “bubble” periods. A “bubble period” is the time a ship closes to personnel transfer while they shelter in place for seven days and undergo COVID-19 testing per NOAA’s Office of Marine and Aviation Operation’s COVID-19 protocol to mitigate exposure. The ship spent the entire first bubble working off the coast of North Carolina and Virginia for this project. These surveys served as a continuation of the ship’s work in the area in the 2019 season. (To learn more about Thomas Jefferson’s work in this area last year, read the 2019 post titled, “NOAA Ship Thomas Jefferson tests innovative DriX unmanned surface vehicle.”

Make your voice heard: Provide input on ocean mapping, exploration, and characterization efforts in the U.S. EEZ

The National Ocean Mapping, Exploration, and Characterization Council (NOMEC Council), a group of federal agencies established to carry out the National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone, requests your input on developing an Implementation Plan and setting strategic priorities for the effort to map the entire U.S. Exclusive Economic Zone (EEZ) by 2040 and explore and characterize strategic areas.
