My fascination with this particular expanse of water shows no sign of ebbing so I was delighted to discover two new (to me!) aspects that have been mapped:
NetSurvey’s High Resolution Seabed Mapping is stunning in its detail and especially interesting as it extends close to the Harris coast between Rodel & Strond.
The oblique view (3rd image from the left ) indicates how Port Eisgein offers the only haven in the South-East corner and suggests to me a site ripe for marine archaeology to explore.
Scottish National Heritage supply us with this PDFon Biotope mapping which is a highly technical document that I do not pretend to completely comprehend but which includes many interesting & attractive maps.
Finally, I heard today from Mapyx QUO that on the 28th of February they are releasing digital versions of UK Hydrographic Maps. No prices or other details have been announced but this is a welcome addition to their collection which is already an excellent and affordable mapping resource.
