There are a load of warnings but I only copied a few that you MA guys might need to know. Lots of areas have severe shoaling "again"...

MA-BOSTON HARBOR (this one was reported last year too)
The Coast Guard has received reports of periodic GPS reception problems occurring east of Boston Harbor in the vicinity of Boston Lighted Whistle Buoy B. Vessels experiencing this problem have witnessed reception problems on single and multiple GPS units. A low level interference source has been detected on the L1 GPS frequency (1575.42 Mhz) in the vicinity of Boston Harbor. Mariners experiencing reception issues on their GPS receivers are requested to contact the Coast Guard Navigation Center at (703) 313-5900 or via email at
tis-pf-nisws@uscg.mil with the model of the affected unit, the duration of the reception issue, and the position the interference was first noticed and when the problem was corrected. Mariners are urged to use caution while transiting the area.
MA-MARTHA’S VINEYARD/NANTUCKET, MUSKEGET CHANNEL
Recent soundings by Coast Guard vessels in the vicinity of the southern entrance to Muskeget Channel show observed water depths that are significantly shallower than charted depths. The National Oceanic and Atmospheric Administration (NOAA) will confirm these soundings during its next regularly scheduled survey of Muskeget Channel. Mariners are urged to consider these observed depths and use particular caution when navigating in the vicinity of the southern entrance to Muskeget Channel.
MA-MARSHFIELD (REVISED 15/13)
Green Harbor Entrance channel has endured multiple storms and has sustained significant shoaling since 2011. Mariners should use extreme caution while transiting the Green Harbor Entrance Channel. The 100 foot channel width has been drastically reduced by recent storms. Mariners are strongly encouraged to AVOID transiting this area 2 hours before Low tide and 2 hours after Low tide. Astronomically Low or Flood tides will have even a greater effect in this area. Maintenance Dredging of the Channel is planned for Late May of 2013.
MA – PAMET HARBOR, TRURO – SEVERE SHOALING
Severe shoaling has been detected at the entrance to Pamet Harbor, Truro, MA, including shoaling within the entrance channel. Mariners are urged to use extreme caution when navigating in the vicinity of the entrance to Pamet Harbor. Additionally, mariners should avoid this area at low tide, and attempt to navigate the Pamet Harbor entrance channel only within three hours before or after high tide.
