Coastal Squeeze, Humber Estuary.
On Friday we did our first bit of fieldwork for the Ocean and Coastal Processes module that we have to do. We jumped on the coach towards Grimsby and Cleethorpes in order to investigate the effects by comparing both sites. Grimsby docks were created in the 19th century resulting in a two way 'coastal squeeze' with both rising sea levels and a manmade structure. It was actually a very fun day and so good to be out in the open air doing some field work, getting a little muddy and wet along the way (it is all part of the fun).
We had split off into two groups. I didn't fancy getting stuck in the mud (I've done it too many times and I end up falling in, something I didn't want to do) and it was a lovely day (photo opportunity as you shall see later) and so I chose to visit the Cleethorpes site. Here we sampled along a transect across the intertidal zone (1000m in Cleethorpes, 400m in Grimsby). Sampling involved taking four core samples (for infauna) and two sediment samples. This was all simple enough at the strandline (where we started) but as soon as we went into the wetter sand it got increasingly more difficult since it was harder to remove from the cores and we were slowly sinking into the quick-sand like surface.

I love this photo with the mounds of sands and the pools of water. This was at about 1000m from the strandline.
