The work will support the Massachusetts Lobstermen’s Association and will involve dissolved oxygen, temperature, and salinity data collection near the approximate center point of 41°50'00\"N, 70°15'00\"W, on Chart 13246. Operations are scheduled to occur 24 hours a day, seven days a week.\nThe vessel, named “Warden,” is a 7-foot autonomous surface vessel with a yellow hull and “Uncrewed / Research Vessel” markings. It will transmit as “Uncrewed” on AIS and will display a flashing amber beacon at night. The vessel may remain stationary for sampling or move at approximately 2 knots between sampling locations during the day. It is not fishing gear and is not intended to interfere with traps, buoys, or lines. Mariners are advised not to approach closely, as the vessel may begin moving without warning. Sedna Robotics can be contacted at any time at 617-506-9177, which is also written on the vessel. If needed to avoid impeding navigation, the vessel can be repositioned within 30 minutes of a phone call to Sedna operations.\n\n","COORDINATES_JSON":"{\"type\":\"Polygon\",\"coordinates\":[[[-70.08308,41.86701],[-70.35465,41.85474],[-70.47653,41.76748],[-70.37697,41.74648],[-70.21148,41.75493],[-70.02643,41.78975],[-70.08308,41.86701]]]}","COORDINATES_TYPE":"Polygon","DECIMAL_LONGITUDE":null,"DECIMAL_LATITUDE":null}},{"type":"Feature","id":52747,"geometry":{"type":"Polygon","coordinates":[[[-74.16548999999998,39.79481000000004],[-74.16551999999996,39.79481000000004],[-74.16906999999998,39.79066000000006],[-74.13682999999997,39.78995000000003],[-74.11958999999996,39.78177000000005],[-74.11777999999998,39.76678000000004],[-74.06863999999996,39.73714000000007],[-74.06221999999997,39.74442000000005],[-74.10817999999995,39.771750000000054],[-74.12112999999994,39.79319000000004],[-74.16548999999998,39.79481000000004]]]},"properties":{"ESRI_OID":52747,"MSI_UID":52747,"ATU":5,"TITLE":"Sector Delaware Bay, Submerged Land Act (SLA) - Barnegat Inlet/General/Miscellaneous","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"Miscellaneous","TYPE":null,"WTRW_UID":100116382918,"MRN":"urn:mrn:iala:wwy:us:navIV:dis5:secdelbayexcecozon:secdelbaytersea:secdelbaysublanact:barinl","WATERWAY_NAME":"Barnegat Inlet","CREATE_DATE":1788275481000,"MODIFIED_DATE":1790248876000,"BEGIN_DATE":1788220800000,"END_DATE":1800143999000,"DESCRIPTION":"General/Miscellaneous\n\nFrom: 2026-09-01 To: 2027-01-16\n\nLocation:\nThe Coast Guard is conducting a Waterways Analysis and Management System (WAMS) review of Barnegat Inlet and Oyster Creek Channel.

More information can be found at: https://quietsound.org/admiralty-inlet-slowdown.  \nWhen in effect, the slowdown requests all inbound and outbound commercial vessels transiting through the slowdown zone not exceed the following speeds through water when safe and operationally feasible:  \n11 knots – General cargo, bulkers and tankers\n14.5 knots – Vehicle carriers, cruise ships, and container vessels\nThe voluntary vessel slowdown takes place in the inbound and outbound lanes of the shipping lanes within these boundaries:\nNorthwest: a line drawn from Pt Hudson (48-07-02.150N, 122-44-56.065W) to Admiralty Head (48-09-15.181N, 122-40-46.211W)\nNortheast: a line drawn from Randall Pt (47-58-59.653N, 122-21-10.336W) to Mukilteo Light (47-56-53.452N, 122-18-28.955W)\nSouth: a line drawn from Apple Cove Pt (47-48-55.926N, 122-28.51.186W) to Edwards Pt (47-48-12.024N, 122-23-41.726W)\nSpeed transition zones are in place about 5 nautical miles prior to entering the slowdown area.\nAny directions from Puget Sound Vessel Traffic Service take precedence and supersede these measures.\nThe voluntary slowdown is led by the Quiet Sound program at Maritime Blue, in cooperation with government agencies, tribal governments, industry partners and conservation groups.

The application, which is accessible at https://www.navcen.uscg.gov/msi, contains the most up to date maritime information overlayed on nautical charts and plotted using latitude and longitude. While the ability to print Local Notice to Mariners and Light List copies is still temporarily available, these printed products lack the positional accuracy of the electronic application and can therefore lead to relevant information being overlooked. Mariners are strongly encouraged to use the Maritime Safety Information Products application as their primary source for all information previously contained in the Local Notice to Mariners and Light List.\n\n","COORDINATES_JSON":"{\"type\":\"Polygon\",\"coordinates\":[[[-90,40.92794],[-84.458,41.06143],[-78.90747,40.92826],[-78.82118,40.99459],[-78.82017,41.92833],[-74.61883,41.93184],[-74.55649,45.01337],[-74.82962,45.0878],[-75.09675,45.0003],[-76.38557,44.24868],[-76.8529,43.70382],[-78.67492,43.70898],[-79.25034,43.51624],[-79.05463,42.86706],[-80.10636,42.46095],[-81.31473,42.26864],[-82.42279,41.75348],[-82.66855,41.75566],[-82.99361,41.90803],[-82.99368,42.26556],[-82.43374,42.57852],[-82.02335,43.58863],[-82.41837,45.35249],[-83.49247,45.79928],[-83.34132,46.03087],[-83.62425,46.19069],[-83.92139,46.16017],[-84.06503,46.59014],[-84.50675,46.54872],[-84.80088,46.94835],[-88.33794,48.37768],[-89.3739,48.05284],[-90.68553,48.15843],[-90.8792,48.31789],[-91.54478,48.12929],[-92.01732,48.42681],[-92.31962,48.32888],[-92.5611,48.5938],[-92.91623,48.69804],[-93.71419,48.59925],[-94.49891,48.78002],[-94.72254,49.35877],[-95.13307,49.45096],[-95.25369,49.3955],[-95.26179,49.07124],[-97.32151,49.04046],[-97.20005,48.67609],[-97.25253,48.13038],[-96.95593,47.58302],[-96.82453,46.42767],[-96.65892,46.27045],[-90.10377,46.26381],[-90.09508,40.99886],[-90,40.92794]],[[-75.74754,44.52845],[-75.73828,44.53519],[-75.72316,44.54628],[-75.71341,44.55411],[-75.72281,44.54649],[-75.7243,44.54528],[-75.72574,44.54411],[-75.72634,44.54351],[-75.72642,44.54343],[-75.72658,44.54328],[-75.72707,44.5428],[-75.73461,44.53745],[-75.73992,44.53375],[-75.74061,44.53327],[-75.74262,44.53188],[-75.74754,44.52845]],[[-75.03231,44.94472],[-75.03106,44.94518],[-75.03093,44.94523],[-75.02967,44.94568],[-75.03092,44.94522],[-75.03105,44.94517],[-75.03231,44.94472]],[[-83.9777,46.09944],[-83.97787,46.09957],[-83.97806,46.09971],[-83.97823,46.09983],[-83.97823,46.09983],[-83.97808,46.09989],[-83.97808,46.09989],[-83.97793,46.09988],[-83.97791,46.09988],[-83.97769,46.09945],[-83.9777,46.09944]]]}","COORDINATES_TYPE":"Polygon","DECIMAL_LONGITUDE":null,"DECIMAL_LATITUDE":null}},{"type":"Feature","id":53356,"geometry":{"type":"Polygon","coordinates":[[[-124.37536999999998,39.24693000000008],[-124.37536999999998,35.30492000000004],[-120.88044999999994,35.30492000000004],[-122.08344999999997,36.276770000000056],[-123.00080999999994,38.106250000000045],[-124.37536999999998,39.24693000000008]]]},"properties":{"ESRI_OID":53356,"MSI_UID":53356,"ATU":11,"TITLE":"NAVAREA XII/General/Miscellaneous","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"Miscellaneous","TYPE":null,"WTRW_UID":100117271030,"MRN":"urn:mrn:iala:wwy:us:navXII","WATERWAY_NAME":"NAVAREA XII","CREATE_DATE":1788973626000,"MODIFIED_DATE":1790011436000,"BEGIN_DATE":1789776000000,"END_DATE":1793750399000,"DESCRIPTION":"Mertech Marine will be conducting cable recovery operations on the M/v Grace (IMO: 9197442\nCall sign: V2ZV5) in the vicinity of off shore Manchester, CA and Morro Bay, CA out to the Exclusive Economic Zone in the following positions:\n\nLatitude\tLongitude\n39.246933\t-124.375367\n38.10625\t-123.00081\n36.27677\t-122.08345\n35.304917\t-120.88045\n35.30492        -124.37537 \n\nThe following list of coordinates are specific positions for work conducted in the vicinity of Manchester, CA:\n\n39.271450\t-124.630750\n39.259600\t-124.470517\n39.246933\t-124.375367\n39.159283\t-123.986033\n39.155200\t-123.946217\n39.007650\t-123.728233\n38.983733\t-123.713850\n38.988900\t-123.731983\n38.969250\t-123.830867\n38.949683\t-123.897567\n38.863600\t-124.082433\n\nWork will begin on September 19th, 2026 and run through until November 2nd, 2026.
