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.

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.

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.”

This week NOAA’s Office of Coast Survey concluded its hydrographic survey response following Hurricane Delta. At the immediate request of the U.S. Army Corps of Engineers (USACE), NOAA’s navigation response teams (NRTs) and NOAA Ship Thomas Jefferson surveyed areas within the Gulf Intracoastal Waterway (GIWW), Calcasieu Ship Channel, and the entrance to the channel. With lessons learned from the response to Hurricane Laura — the first major hurricane of the 2020 season and the first hurricane response during a pandemic — the teams and Thomas Jefferson successfully collected, processed, and delivered data to the USACE, identifying significant hazards to navigation and helping to ensure the timely reopening of waterways.

On May 28, 2020, four uncrewed vessels departed Alameda, California, to begin their transit across the Pacific Ocean, through Unimak Pass, across the Bering Sea, and into the Arctic. These small, uncrewed vessels, powered only by wind and sun, arrived at Point Hope, Alaska, in early August to start an ambitious project acquiring new depth data along the 20 and 50 meter depth contours from Point Hope to the Canadian border. This was the start of a challenging Arctic project that would contend with weather, sea ice, and equipment failures, all while avoiding potential conflicts with indigenous subsistence hunting.

Hurricane Laura, the first major hurricane of the 2020 Atlantic Hurricane Season, made landfall over Louisiana in the early morning hours of Thursday, August 27. As a Category 4 storm and with maximum sustained winds reaching 150 miles per hour, it caused significant damage along the Gulf coasts of Louisiana and southeastern Texas. For NOAA’s Office of Coast Survey – whose job it is to identify dangers to navigation and help speed the reopening of ports and waterways following severe storms – this marked the first hydrographic survey response effort of the hurricane season.

This week, NOAA’s Office of Coast Survey released the Mapping U.S. Marine and Great Lakes Waters: Office of Coast Survey Contributions to a National Ocean Mapping Strategy. This report is part of NOAA’s ongoing commitment to meet core surveying and nautical charting mandates while supporting broader needs to fill gaps in seafloor mapping and environmental sciences.

NOAA’s Office of Coast Survey, United States Coast Guard (USCG) Sector Honolulu, State of Hawaii Department of Transportation and United States Army Corps of Engineers (USACE) Honolulu Division established a memorandum of understanding (MOU) outlining each signatory’s area of responsibility in the event of a disaster in the Hawaii region. The intent of the MOU is to improve the efficiency and effectiveness of response efforts and speed the reopening of the ports and waterways following an emergency.

There are many benefits to working on a hydrographic survey project for NOAA’s Office of Coast Survey. Some would say having the opportunity to visit amazing landscapes, work with talented people, and collect important environmental data are just a few of them. Recently, Coast Survey’s Hydrographic Surveys Division hosted an internal photo contest inviting employees and contractors to submit images in the categories of Ships and Boats, Landscapes, People, and Data. On this Earth Day 2020, we thought we would share our contest winners with you.

When I traveled around Europe as a young man, my first stop upon leaving the train station in a new city was at the tourist bureau kiosk for a paper city map. On a recent trip to Malaysia, I used my phone to find walking instructions to a street market across town. When I arrived, I described my route to my host, who said that the pedestrian bridge I had used only opened the week before.
