Dashli volcanic eruption: Do mud volcanoes affect hydrological processes?

Posted on August 26, 2022 by Young Hydrologic Society

A Streams of Thought contribution by Hayat Nasirova.

“Mud volcano” is a generic term commonly used to describe any structure that emits water, mud, or hydrocarbons. Although mud volcanoes occur most commonly offshore, onshore mud volcanoes also exist in selected localities, generally in compressional tectonic settings (Milkov, 2000; Kopf, 2002). The petroleum bearing Caspian basin (CB) is located within the Alpine-Himalayan mobile tectonic belt, where earthquakes and intense modern earth crust movements have been observed. CB is a relic of the Tethys Ocean originating in the post-orogenic stage of regional development. It is an intermountain basin surrounded by mountain systems: Great and Lesser Caucasus, Talysh, Elburs, Kopetdag and Balkhan (Feyzullayev, 2012).

Dashli Island is one such island formed by a mud volcano. It was discovered in the 18th century by Russian sailors under Peter the Great who named it “St. Ignatius Stone”, after Ignatius of Antioch. The Dashli mud volcano emits hotbeds of polyaromatic hydrocarbons (PAHs) with continuous methane discharge as well (Remizovschi and Carpa, 2021).

How to write a review article in Hydrology – EGU 22 Short course

Posted on May 27, 2022 by Young Hydrologic Society

One of the fundamental drivers of scientific progress is research integration and synthesis, which is essentially beneficial for developing a research vision. Hence, literature reviews prove to be highly useful to many researchers at all academic stages. Analysing the literature and writing reviews for a thesis, article or project proposal can sometimes be challenging to fresh early-career scientists. For a review paper, even greater attention must be given to the methodological approach to conduct a reproducible and thorough review of the existing scientific literature.

EGU 22 Short Course: Scientific visualisation: Visualise your data effectively and avoid common pitfalls

Posted on May 26, 2022 by Young Hydrologic Society

On Thursday, 26 May, YHS organized a short course at EGU 2022 in a hybrid format, where Lina Stein, Edoardo Martini, Swamini Khurana, with inputs from Navid Ghajarnia and Sarah Schneeman (Copernicus Imaging team) presented salient features of scientific visualisation and how to create publication ready figures using R and python. Guillaume Vigouroux demonstrated how Inkscape can be used to make simple edits without going back to the code, and to combine numerous figures into one figure.

The course materials are available below:

Profile Series: Shashank Bhushan (he/him)

Posted on May 23, 2022 by Young Hydrologic Society

Let’s get the basics. Name, where you are from, and your current affiliation and advisor?

Hi, I am Shashank Bhushan, I grew up in Patna, Bihar, a city located in the floodplains of the river Ganges in India. I am currently a PhD student in Civil and Environmental Engineering at the University of Washington. I am advised by Dr. David Shean.

What is the research you are currently working on?

For my PhD dissertation, I have been learning and improving methods to derive high resolution topographic maps of the Earth’s surface from satellite imagery. If we have two or more of these topographic maps computed from images acquired at different times but over the same region, we can compare them to accurately measure the changes in the ground surface over that particular region! For the “science” component of my thesis, I use this technique to study the surface evolution of High Asia glaciers, document the rates at which the glacier ice is thinning or thickening, and analyze how fast or slow these glaciers are moving.
