Structure from Motion (SfM) has wide application across the fields of robotics, media, and geography. In this course, you will learn the principles of SfM using open-source (freely-available) software to create our own 3D models.
In this course, we will get comforable using R through a series of four tutorials covering the basics, data wrangling, creating plots, and statistical examination of data.
A short film about how the tides work – as Sir Issac Newton envisaged them over 300 years ago.
The Mini Buoy is a low-cost and easy-to-assemble device that measures currents, waves, and tides using accelerometers.
Salt marshes are ephemeral landscapes, which commonly erode and expand by tens of metres a year. Understanding historical patterns of marsh change and identifying the drivers which cause change can help predict how marshes will likely change in the future.
Coastal plants engineer their surrounding environment to increase changes of survival. Depending on how energetic the environment is, plants that use different survival strategies might emerge – ones that are resistant to erosion, and others that reinforce it.
Marshes sit on a knife-edge. It only takes a small change in wave exposure, current velocity, or tidal inundation to cause the marsh edge to expand or erode. This project is searching for the point at which hydrological forcing tips the marsh edge from an expanding to an eroding state.
In August 2014, the seawall at Cwm Ivy on the northern Gower peninsula failed and the land behind was once again connected to the sea. The landscape is changing rapidly as saltmarsh plants replace grasslands, new channels propagate, and old marshes erode – making this the first restored marsh in Wales.
For centuries, saltmarshes around the world have been lost to land claim. What’s left is now threatened by climate change and use of the coast by people. My review discusses the latest knowledge on the processes of saltmarsh expansion and erosion, and how attitudes towards saltmarsh management have changed over the years.
