Change of command for NOAA Ship Thomas Jefferson

Capt. Chris van Westendorp and Cmdr. Briana Welton Hillstrom salute with Capt. Zezula looking on.

On April 12, 2019, the crew of NOAA Ship Thomas Jefferson hosted a change of command in Brooklyn, NY. Cmdr. Briana Welton Hillstrom accepted command of Thomas Jefferson, relieving Capt. Christiaan van Westendorp in a ceremony led by Capt. David Zezula, commanding officer of NOAA’s Office of Marine and Aviation Operations (OMAO) Marine Operations Center-Atlantic.

U.S. Coast Pilot® now contains Navigation Rules

NOAA recently announced that all nine United States Coast Pilot®  volumes now contain the U.S. Coast Guard International Regulations for the Prevention of Collisions at Sea (72 COLREGS) and the Inland Navigation Rules — commonly known as the “Rules of the Road.” The navigation rules are similar to rules on the highway as they present a consistent way to navigate safely and avoid collisions. Having the newly published Coast Pilot now fulfills the legal requirement for mariners to maintain a copy of these regulations on board.

Tankers, Freighters, and….Kayaks?

From tankers to kayaks, NOAA nautical chart products offer something for all types of users.

By Nick Perugini

It is not an exaggeration to say that ALL types of vessels use NOAA charts.  We know that large commercial ships, such as tankers and freighters, rely on NOAA charts in U.S. waters, and for that matter, so do recreational boaters. But kayakers? Some of the most enthusiastic and appreciative comments we receive are sent to us by kayakers. The following are a few examples. Continue reading “Tankers, Freighters, and….Kayaks?”

NOAA Improves Etolin Strait Data with New NOAA ENC® Layout

Etolin Strait survey area and reschemed grid

NOAA recently released 13 new large-scale electronic navigational charts (NOAA ENC®) of Etolin Strait, Alaska. These charts provide a nearly twenty-fold increase in scale over the previous ENC coverage. New Etolin Strait hydrographic surveys and the resulting ENCs served as a pilot project for the overall rescheming of the entire NOAA ENC suite with a regular, gridded layout for ENC charts, as outlined in NOAA’s National Charting Plan. No corresponding NOAA raster nautical chart products in Etolin Strait will be produced. This is in keeping with Coast Survey’s “ENC-only” production concept, which generally maintains the current raster chart product coverage, but only creates new larger scale coverage in the ENC product line.

NOAA announces change in channel depths on raster nautical chart products

Ships passing on the lower Mississippi River.

NOAA’s Office of Coast Survey recently announced plans to change the U.S. Army Corps of Engineers (USACE) maintained channel depth values on raster nautical chart products, which include paper nautical charts and the corresponding digital raster navigational charts (NOAA RNC®). Minimum depths (also called controlling depths) are collected during periodic USACE sonar surveys of channels. In the past, these depths were provided on raster charts, but controlling depths will now be replaced with the original channel design dredging depths used by the USACE (called project depths). Standardizing depth presentation on these products will improve data consistency and overall safety. Implementation begins in early 2019.

nowCOAST® offers new Gulf of Maine, Chesapeake Bay forecast services

Depiction of NOS Vv probability of occurrence forecast guidance for Chesapeake Bay on nowCOAST map viewer.

NOAA’s nowCOAST®, a GIS-based online web mapping service that provides frequently updated weather and ocean observations, analyses, imagery, and ocean model forecast guidance, along with weather watches and warnings and forecasts, now provides maps of oceanographic forecast guidance from the National Ocean Service (NOS) 3-D operational forecast modeling system for the Gulf of Maine (GoMOFS) and NOS forecast guidance of the marine pathogen, Vibrio Vulnificus (Vv), for the Chesapeake Bay via two new map services and map viewer.

NOAA Ship Thomas Jefferson tests drone use for shoreline mapping

By, Lt. j.g. Matt Sharr, NOAA, and Lt. Charles Wisotzkey, NOAA

NOAA’s Office of Coast Survey and the National Geodetic Survey (NGS) recently conducted operational tests of small unmanned aerial systems — or drones — on board NOAA Ship Thomas Jefferson in support of survey operations conducted along the south coast of Puerto Rico. The tests show the potential of imagery from low-cost off-the-shelf drones to meet NOAA survey specifications for near-shore and shoreline feature mapping. This could replace traditional shoreline verification and mapping techniques used by NOAA hydrographic survey field units. Potential benefits of using drones for shoreline mapping include: improved data collection efficiency compared to data collection from small skiffs; more accurate feature investigation than traditional techniques; and, most importantly, removal of personnel from potentially dangerous situations (i.e. survey in close proximity to features being mapped).

NOAA makes it easier to submit a comment or report a nautical chart error

On November 16, 2018, NOAA released ASSIST, a new system for submitting questions and reporting nautical chart errors to NOAA’s Office of Coast Survey. ASSIST has a mobile-friendly design and improved user interface that allows customers to access the system conveniently from any device. This new tool replaces Coast Survey’s Inquiry and Discrepancy Management System (IDMS), a database that collected nearly 20,000 comments, inquiries, and discrepancy reports since 2008. ASSIST is available from: https://www.nauticalcharts.noaa.gov/customer-service/assist/ Continue reading “NOAA makes it easier to submit a comment or report a nautical chart error”

Seismic inter-agency collaborations on NOAA Ship Rainier

NOAA Ship Rainier spent September completing a multi-leg, joint collaboration project investigating deep offshore areas of the southern California coast. The U.S. Geological Survey (USGS) and Bureau of Ocean Energy Management (BOEM) partnered with NOAA to support a month-long mission to collect geophysical data along the outer continental shelf of California where the area in question features a number of different geologic structures and processes.

NOAA Ship Thomas Jefferson successfully tests new wireless system that aids remote vessel operation

By Lt. Charles Wisotzkey, NOAA

NOAA Ship Thomas Jefferson successfully tested a new wireless networking system while working in the Approaches to Houston/Galveston and around Puerto Rico during the 2018 field season. This new system connects the ship and its two hydrographic survey launches, providing a level of wireless connectivity previously unobtainable with traditional wireless communications systems. NOAA anticipates this will increase unmanned system productivity while conducting hydrographic surveys.
