North Iceland Glacier Inventory - 1975 Field Season
The reports of three groups have been sub-
mitted and are summarised below.
Gljúfurárjökull (Leader: David Levy, John
Leggott College). The map of the snout of
Gljúfurárjökull was repeated so that we now
have maps for 1973, 1974 and 1975. There is
some disagreement between the accuracy of the
maps for 1974 and 1975 but although parts of
the snout have receded it seems clear that no
noticeable retreat can be recorded for 1974/75.
Retreat for 1973/74 was approximately 115 m.
Long profiles were repeated. This group also
visited and completed data sheets for nine other
glaciers. Ultimately this information will appear
in the monograph on Svarfadardalur and Skída-
dalur (Basin 05/D).
Thverárjökull (Leader: Derek Longley, Eves-
ham High School). Once again the survey was
hindered by extensive snow cover and results
were not satisfactory. This type of glacier clear-
ly is unsuitable for long-term monitoring. In-
ventory data sheets were partially completed for
four glaciers while two other glaciers were ex-
amined from a distance.
Thorvaldsdalur (Leader: Serena Bridges, Brit-
ish Girl’s Exploring Society). A thorough ground
reconnaissance was carried out by this group,
but because of snow cover no ‘jöklamerki’ were
inserted. Their report will probably be the first
monograph resulting from the North Iceland
Glacier Inventory project and should appear
after a further season’s work. At the moment
the data is being analysed by Dr. Nigel Griffey
at the University of Sheffield Department of
Geography who has located four more glaciers
and a rock glacier. The group had to modify
the glacier numbering given on the map pu-
blished in the 1974 issue of Jökull and have
divided the basin as follows:
Group 1: The glaciers El, E2, and E3 contri-
buting to the river Thverá. A large perennial
snow patch is also recorded.
Group 2: The glaciers E4 to E9 contribute to
the valley drained by the Fremri-Lambá and
Nautá. Field observation has added two other
glaciers to this basin.
Group 3: Strictly these three glaciers (F1 to F3)
belong to the Hörgá—Öxnadalsá basin (Basin
05/F) but for the purposes of this survey will
be included in the monograph. Glacier F2
(Dýjajökull) was not recorded on the original
map where F2 was what is now F3.
Barkárdalur (Leader: Clive Hudson, Plas
Gwynant Outdoor Education Centre). A tho-
rough ground reconnaissance has shown the ice
masses of Barkárdalur to be more numerous
