The effect of sampling effort on estimates of methane ebullition from peat (2017)
Journal Article
Ramirez, J. A., Baird, A. J., & Coulthard, T. J. (2017). The effect of sampling effort on estimates of methane ebullition from peat. Water Resources Research, 53(5), 4158-4168. https://doi.org/10.1002/2017wr020428

© 2017. American Geophysical Union. All Rights Reserved. We investigated the effect of sample size and sampling duration on methane bubble flux (ebullition) estimates from peat using a computer model. A field scale (10 m), seasonal ( > 100 days) simu...

The effect of pore structure on ebullition from peat (2016)
Journal Article
Ramirez, J. A., Baird, A. J., & Coulthard, T. J. (2016). The effect of pore structure on ebullition from peat. Journal of Geophysical Research: Biogeosciences, 121(6), 1646-1656. https://doi.org/10.1002/2015jg003289

The controls on methane (CH₄) bubbling (ebullition) from peatlands are uncertain, but evidence suggests that physical factors related to gas transport and storage within the peat matrix are important. Variability in peat pore size and the permeabilit... Read More about The effect of pore structure on ebullition from peat.

Hyper-resolution mapping of regional storm surge and tide flooding: comparison of static and dynamic models (2016)
Journal Article
Ramirez, J. A., Lichter, M., Coulthard, T. J., & Skinner, C. (2016). Hyper-resolution mapping of regional storm surge and tide flooding: comparison of static and dynamic models. Natural hazards, 82(1), 571-590. https://doi.org/10.1007/s11069-016-2198-z

Storm tide (combination of storm surge and the astronomical tide) flooding is a natural hazard with significant global social and economic consequences. For this reason, government agencies and stakeholders need storm tide flood maps to determine pop...

Ebullition of methane from peatlands: does peat act as a signal shredder? (2015)
Journal Article
Ramirez, J. A., Baird, A. J., Coulthard, T. J., & Waddington, J. M. (2015). Ebullition of methane from peatlands: does peat act as a signal shredder?. Geophysical research letters, 42(9), 3371-3379. https://doi.org/10.1002/2015gl063469

Bubbling (ebullition) of greenhouse gases, particularly methane, from peatlands has been attributed to environmental forcings, such as changes in atmospheric pressure. However, observations from peat soils suggest that ebullition and environmental fo... Read More about Ebullition of methane from peatlands: does peat act as a signal shredder?.

Simulating tidal and storm surge hydraulics with a simple 2D inertia based model, in the Humber Estuary, U.K (2015)
Journal Article
Skinner, C. J., Coulthard, T. J., Parsons, D. R., Ramirez, J. A., Mullen, L., & Manson, S. (2015). Simulating tidal and storm surge hydraulics with a simple 2D inertia based model, in the Humber Estuary, U.K. Estuarine, coastal and shelf science, 155(March), 126-136. https://doi.org/10.1016/j.ecss.2015.01.019

The hydraulic modelling of tidal estuarine environments has been largely limited to complex 3D models that are computationally expensive. This makes them unsuitable for applications which make use of live data to make real/near time forecasts, such a...

Were rivers flowing across the Sahara during the last interglacial? Implications for human migration through Africa. (2013)
Journal Article
Coulthard, T. J., Ramirez, J. A., Barton, N., Rogerson, M., & Brücher, T. (2013). Were rivers flowing across the Sahara during the last interglacial? Implications for human migration through Africa. PLoS ONE, 8(9), 0-0. https://doi.org/10.1371/journal.pone.0074834

Human migration north through Africa is contentious. This paper uses a novel palaeohydrological and hydraulic modelling approach to test the hypothesis that under wetter climates c.100,000 years ago major river systems ran north across the Sahara to...

Integrating the LISFLOOD-FP 2D hydrodynamic model with the CAESAR model: implications for modelling landscape evolution (2013)
Journal Article
Coulthard, T. J., Neal, J. C., Bates, P. D., Ramirez, J., de Almeida, G. A., & Hancock, G. R. (2013). Integrating the LISFLOOD-FP 2D hydrodynamic model with the CAESAR model: implications for modelling landscape evolution. Earth surface processes and landforms : the journal of the British Geomorphological Research Group, 38(15), 1897-1906. https://doi.org/10.1002/esp.3478

Landscape evolution models (LEMs) simulate the geomorphic development of river basins over long time periods and large space scales (100s-1000s of years, 100s of km2). Due to these scales they have been developed with simple steady flow models that e...

Vertical density gradient in the eastern North Atlantic during the last 30,000 years (2011)
Journal Article
Rogerson, M., Bigg, G. R., Rohling, E. J., & Ramirez, J. (2012). Vertical density gradient in the eastern North Atlantic during the last 30,000 years. Climate Dynamics, 39(3-4), 589-598. https://doi.org/10.1007/s00382-011-1148-4

Past changes in the density and momentum structure of oceanic circulation are an important aspect of changes in the Atlantic Meridional Overturning Circulation and consequently climate. However, very little is known about past changes in the vertical... Read More about Vertical density gradient in the eastern North Atlantic during the last 30,000 years.
