Controls on submarine landslide formation: the key role of weak layers

Ricarda Gatter - University of Bremen

26/01/2022 4:00 pm (London)

Submarine landslides are gravity-driven mass movements that occur in underwater slope settings worldwide. Despite their potential to damage expensive seafloor infrastructure such as pipelines or telecommunication cables and to generate hazardous tsunamis, many aspects of submarine landslide formation remain poorly understood. Many studies have proposed that the formation of submarine landslides on seemingly stable slopes may be explained by weak layers within the slope stratigraphy. Our understanding of weak layers, especially their compositional and structural characteristics, however, is restricted due to often limited data availability and resolution. This talk will focus on the integration of datasets at different scales and resolution in order to both qualitatively and quantitatively investigate the role of sediment structure and composition on weak layer and submarine landslide formation.

It’s a jungle out there! How big data can help resolve regional palaeogeographies in tropical climates

Amy Gough - Royal Hoilloway, University of London

Tropical climates, such as SE Asia, can lead to poor exposure and heavily weathered outcrops. Whilst fieldwork can give an important insight into the underlying geology, detailed detrital analysis is essential to fill in the gaps. Here, a combination of light minerals, heavy minerals, and detrital grain ages from around SE Asia are used to try to reconstruct palaeogeographies in an area of complex tectonics.

Toasty coasts in high-CO2 worlds: Marine mollusks as paleo-weathermen?

Niels J. de Winter - Utrecht University

16/02/2022 4:00 pm (London)

The ongoing global Climate Crisis has sparked a strong interest in climate reconstructions and models of geological periods with high atmospheric CO2 concentrations.
But how much do we really now about the dynamics of Earth’s past climate and coastal ecosystems on the human timescale?
Now that concern is rapidly rising about the catastrophic effect of extreme weather events and seasonality, especially to our sensitive and economically important coastal areas, biogenic carbonate producers like mollusks (clams and snails) rise to the occasion as ideal archives for environmental and ecosystem change at the timescale that matters: days to decades.
In this talk, I will try to answer the question: What can these beautifully preserved shells teach us about the occurrence of extreme weather and seasonality under various climate states?
