We record the surface conditions at dune research sites with photographs,
notes and sketches. In all seasons, we record if sand is moving
while we are at the site.
Summer records include
the condition of the vegetation and the presence of ripples which
indicate recent sand movement.
Autumn records include
visible variations in moisture across the beach and dunes and interesting
features like sand pillars or adhesion ripples. We also record patterns
of recent sand movement such as streamlined deposits of sand.
Winter records include
the areas of exposed sand, snow cover, niveo-aeolian deposits and
surface ice. We measure snow depths and record whether exposed sand
is frozen or not. We use erosion pins as reference markers for our
observations.
Spring records include
areas of melting snow, thawing niveo-aeolian deposits, and evidence
of mass wasting (slumping, sliding) as slopes adjust to warm conditions. |
