Sediment in the deep ocean, Part 1: flows that shape the seafloor.

Sediment in the deep ocean, Part 1: flows that shape the seafloor.

Most of us know about the existence of waves and tides. We can see them along our coasts and, even if we do not pay much attention, we also know that waves and tides move sediment that rests on the seafloor: sand, mud, shells and…plastics. We all can see ripples and small channels on beaches or estuaries created by the movement of water from waves and tides. If we scuba dive down to a few tens of ...[Read More]

Open your heart, science and data – and welcome Res. 42 by WMO

Open your heart, science and data – and welcome Res. 42 by WMO

Boundaries and limits. Everyone had a pleasant and rich (hopefully) taste of these concepts in 2020. Time-wise, workwise, and heart-wise among many others. Openness, tolerance and love. Everyone rightfully acknowledged the dearness of these feelings (probably) at the utmost level, again in 2020 – a year quite likely to be remembered as one of those soul-shattering years in the human history. Why d ...[Read More]

New metric to interpret linear trends from short time series: Trend to variability ratio (TVR)

  Availability of good quality data is essential to deduce meaningful information in all disciplines of science and technology. This statement is especially relevant in climate research, which is under constant scrutiny from sceptics. In order to better understand the Earth system response to the ongoing anthropogenic global warming, we require global observations of climate indicators at ver ...[Read More]

NPG Paper of the Month: “Ordering of trajectories reveals hierarchical finite-time coherent sets in Lagrangian particle data: detecting Agulhas rings in the South Atlantic Ocean”

The February 2021 NPG Paper of the Month award goes David Wichmann and his co-authors for their paper “Ordering of trajectories reveals hierarchical finite-time coherent sets in Lagrangian particle data: detecting Agulhas rings in the South Atlantic Ocean“. Understanding the transport of tracers and particulates is an important topic in oceanography and in fluid dynamics in general. Th ...[Read More]

Do you know about OGGM-Edu? An open-source educational platform about glaciers and glacier modelling

Are you teaching about glaciers and looking for fun educational activities for your students? Are you planning a workshop about glacier modelling and want to make it interactive, with a low entry level? Are you interested in learning about glaciers and glacier modelling, and looking for a simple way to get started? On top of that, do you want to do all of the above without installing anything on y ...[Read More]

The Sassy Scientist – Growing Pains

Despite the emergence of some minor ailments, Antti is still going strong with his research. With a slight declination in his productivity levels whilst stubbornly grunting along, he feels he should (and perhaps could) do better. Annoyed, he growls: Academia has cost me my 20/20 vision (and given me a sore ass). Who do I blame? Dear Antti, Blame me. I apologize unreservedly for prolonging your scr ...[Read More]

TS Must-Read – Davis et al. (1983) Mechanics of Fold-and-Thrust Belts and Accretionary Wedges

The establishment of plate tectonics in the 1960s triggered a reappraisal of the development of mountain belts and facilitated the physics-based understanding of mountain building processes. Many models for mountain building were, however, mostly conceptual, and there was no appropriate theory that described the first-order mechanics of mountain belts. In 1983, this gap was – at least partially – ...[Read More]
