Two new current meters mounted on tripod cages, one close inshore of Wissant (between Gris-Nez and Calais), the second, due north of the east Graveslines harbour pier.  I have marked them as unlit yellow buoys but precisely how they appear are unknown to me!  The meter off Wissant is perhaps so close to the shor that it is unlikely to be encountered by us BUT off Gravelines is likely to be encountered if approaching to entered from the direction of the east.  Two images.

A bit unusual: three reductions of depth/new drying heights.  Two on the edge of Blacktail Spit (off Shoeburyness) between the South Shoebury SHB and the Blacktail Spit SHB and one drying height at the Deben Entrance.  I notice the source is from the Environment Agency NOT from Trinity House.  I suspect this might not be immediately recent and we should wait for the details from Trinity House which will be announced by East Coast Pilot as soon as they have the new chartlet.  Note the image at the Deben will be out of date, it is merely used to show where the drying height is recorded.
