Article
Attempts to understand the morphodynamics of rock coasts focus on the nature and rate of erosion and how this influences the evolution of coastal profiles over century to millennial timescales. Biological contributions to this process are often ignored or treated in a rather simplistic way as merely producing microscale decreases in rock strength....
Article
Understanding the complex, non-linear ways in which linked ecological and geomorphological systems respond to disturbance is important to improving both theoretical understanding and practical environmental management. Some simple conceptual models have been proposed to describe biogeomorphological responses to disturbance within fluvial and aeolia...
Article
Although biogeomorphological research is well-established, with many studies on a range of two-way interrelations between organisms and geomorphology in different environments, there is little consensus over what constitutes biogeomorphology, why it might be useful and where it is heading. Starting with definitions of core biogeomorphic processes,...
Article
In this paper, we quantitatively demonstrate that dominant erosion processes on different shore platforms can be explained, in part, by geological properties. We selected sites with a considerable history of rock coast geomorphology study, to evaluate whether geological data can improve our understanding of spatial variations in erosion between sit...

Full-text available
Public satellite platforms offer regular observations for global coastal monitoring and climate change risk management strategies. Unfortunately, shoreline positions derived from satellite imagery, representing changes in intertidal topography, are noisy and subject to tidal bias that requires correction. The seaward‐most vegetation boundary reflec...

Achieving the UN Sustainable Development Goals may only be possible if human activities are central to critical zone science.
Article
Full-text available
There is a growing global emphasis on sustainable agriculture to reduce human impacts and improve delivery of Sustainable Development Goals (SDGs). With increasing investment in critical zone observatories (CZOs), it becomes important to understand how sustainable agricultural knowledge is produced, shared and used between different groups includin...
Article
Full-text available
Critical Zone Science (CZS) explores the deep evolution of landscapes from the base of the groundwater or the saprolite‐rock interface to the top of vegetation, the zone that supports all terrestrial life. Here we propose a framework for CZS to evolve further as a discipline, building on 1st generation CZOs in natural systems and 2nd generation CZO...
Article
Full-text available
Hard coastal defences support lower biodiversity than natural rocky shores. Ecological enhancement on coastal structures can improve biodiversity by increasing habitat heterogeneity. Most studies have investigated the effect of only one type of texture on intertidal biodiversity. There is a lack of eco-engineering designs that mimic the complexity...
Chapter
Estuarine and coastal ecosystems support high biological productivity and provide important societal benefits including food production, carbon sequestration and alleviating erosion and flood risks for coastal communities. Coastal systems respond dynamically to changing conditions where they are unconstrained by artificial assets and infrastructure...
Conference Paper
Full-text available
Shoreline positions reflect the underlying morphology of the beach and can act as an indicator of changes in wave climate and sediment transport across a beach system. However, the ever-moving nature of the shoreline means the instantaneous measure can pose tidal biases and noise problems in seasonal timeseries. The seaward- most boundary of vegeta...
Conference Paper
Full-text available
This study developed a series of new, semi-automated methods for quantitatively analysing the contribution of rock weathering processes and geological control on shore platform evolution and boulder production. We used high resolution Digital Surface Models (DSMs) and orthoimages to map and classify a series of geomorphological and geological contr...

ABSTRACT Up to 19% of Scotland’s varied and dynamic coast is classified as soft and potentially erodible. These soft coasts are under increasing risk of coastal erosion and coastal flooding, driven by observed sea level rise (predicted to accelerate) and by potential changes in storm wave impact. We present here a method to quantitatively predict c...

The majority of shore platforms form in rocks that are characterised by layered stratigraphy and pervasive jointing. Plucking of weathered, joint and bed bounded blocks is an important erosion process that existing models of platform development do not represent. Globally, measuring platform erosion rates have focused on microscale (< 1 mm) surface...
Article
Full-text available
Understanding social-ecological system (SES) feedbacks and interactions is crucial to improving societal resilience to growing environmental challenges. Social-ecological systems are usually researched at one of two spatial scales: local placed-based empirical studies or system-scale modelling, with limited efforts to date exploring the merits of c...

Full-text available
Karst aquifers have distinctive hydrology and supply 25% of the world's population with drinking water, making them a critical geological setting for understanding and managing microbial water pollution. Rainfall causes elevated concentrations and loading of faecal microorganisms, e.g. E. coli, in catchment surface and groundwater systems, increasi...
Article
In order to enhance the ecological value of vertical hard coastal structures, hybrid designs with complex surface textures (such as a combination of grooves and pits) have been recommended. This strategy optimises ecological colonisation at two spatial scales: 1) at the mm-scale for barnacle abundance (shown to have bioprotective capabilities), and...
Article
Large boulder-size clasts can represent important archives of high energy erosional wave activity at the coast. From tropical coral reefs to high-latitude eroding cliffs, boulders have been used to hindcast the frequency and magnitude (height) of waves produced by both storms and tsunami. Such reconstructions are based on the balance between the hy...

Article
Full-text available
Extensive development and construction in marine and coastal systems is driving a phenomenon known as “ocean sprawl”. Ocean sprawl removes or transforms marine habitats through the addition of artificial structures and some of the most significant impacts are occurring in sedimentary environments. Marine sediments have substantial social, ecologica...
Article
Sedentary and mobile organisms grow profusely on hard substrates within the coastal zone and contribute to the deterioration of coastal engineering structures and the geomorphic evolution of rocky shores by both enhancing and retarding weathering and erosion. There is a lack of quantitative evidence for the direction and magnitude of these effects....

Rocky landforms dominate large portions of the world’s coast. Cliffs and shore platforms form spectacular landscapes, yet when compared to other landforms they are relatively unstudied with many contemporary controversies dating back to the mid-nineteenth century. The past decade has seen a reinvigoration of research driven by advances in technolog...
Article
Non-destructive tools capable of measuring the condition and geomechanical properties of construction materials through time are of considerable value in engineering. Here, the ability of the Equotip durometer (Proceq, type D) to detect changes in the hardness of concrete and rock exposed to marine conditions was tested. Results indicated a progres...
Article
As well as their destructive roles, plants, animals and microorganisms contribute to geomorphology and ecology via direct and indirect bioprotection, which can reduce weathering and erosion. For example, indirect bioprotection can operate via biotic influences on microclimate whereby physical decay processes associated with fluctuations in temperat...
Article
Urbanisation is recognised as a major pressure on coastal biodiversity. Increasing risks of flooding and erosion associated with future climate change indicate that new hard infrastructure will have to continue to be built – and existing structures upgraded – in areas of high social and economic value. Ecological enhancement involves undertaking ma...
Article
Bioerosion on rocky shores has been frequently reported as an important mechanism in coastal evolution, with less attention focussed on determining the bioprotective role organisms may have in mediating coastal erosion. This work aims, for the first time, to provide an integrated assessment of both traversing microerosion meter (TMEM) downwearing r...
Article
The way in which rocks and engineering materials heat‐up and dry‐out in the intertidal zone is of relevance to both weathering and ecology. These behaviours can be measured in the laboratory under controlled conditions designed to replicate those occurring in the field. Previous studies have demonstrated differences in thermal behaviours between ro...
Conference Paper
Full-text available
The direct roles of microorganisms in the breakdown of rock and stone are well recognised. The ways in which animals, plants and microorganisms modify the efficiency of other weathering processes (both positively and negatively) are less well studied. Recently, macro-organisms (e.g., ivy and seaweed) have been suggested to have a bioprotective func...

Article
There is growing research suggesting that coastal boulders can be entrained, transported and deposited by storm events as well as tsunamis. This research has typically documented decadal to century timescale changes in intertidal, supra-tidal or cliff-top boulder deposits. Indeed, there are no known studies of contemporaneous boulder transport stud...
Article
The majority of coastal sediment transport studies focus on material finer than coarse gravels. Likewise, sediment fingerprinting as well as tag and trace technologies tend to focus on finer grained materials. In our paper, we present a methodology for tagging and tracing much larger materials - intertidal boulders weighing up to 0.75 tons. Whilst...
