News from the PAG Drilling Team

After a few difficult days with several attempts to drill and recover the sediments of the clay pan PAG, the team reached 41m with full recovery. The tough environment and sediments brought some major difficulties with it. The drill team changed from sonic-drilling to conventional drilling. A thick cemented tephra layer at 31m stopped the first drill hole.

Scientific meeting with SERNAGEOMIN

On Friday the 6th of October, geologist from the Chilenean Geological Survey (SERNAGEOMIN, Paulina Vasquez and Fernando Sepulveda Vasquez), from the UCN (Eduardo Campus), from the US (Tereca Jordan) and from Germany (Tibor Dunai, Benedikt Ritter, Volker Wennrich) organized a small meeting in Hornitos to discuss recent scientific progress in the area around the southern Río Loa and the Quillagua-Llamara basin.

Official ceremony and execution of the Memorandum of Understanding

On Friday the 16.09.2017 the Universidad Catolica del Norte (UCN) represented by the rector of the UCN Jorge Tabilo Álvarez and the CRC1211, represented by Prof. Tibor Dunai ceremonial signed the Memorandum of Understanding between the UCN and CRC1211. Both parties are looking forward for a prolonged scientific collaboration and a fruitful exchange between Chilean and German scientists.


Second field campaign of D03

In September 2017 we carried out our second field trip to the Atacama Desert to investigate the local hydrological situation at the Salar de Llamara and the Salar de Huasco.

Investigations at the Salar de Llamara started in the preliminary phase of the CRC 1211. Isotope analyses of pond waters from 2014 show that the isotopic evolution of the ponds can be reproduced by evaporation models, but further parameters such as the isotopic composition of atmospheric vapor and the influence of wind, need to be characterized more precisely.

Second field campaign of Z2 and Z3 ...

... with focus on the installation of weather stations, the realization of irrigation experiments, and the installation of dust sampling devices. During the second field campaign in September-October 2017, PhD student Franko Arenas Díaz from Universidad Catolica del Norte (UCN – Antofagasta) accompanied Z2 and Z3. We were able to successfully set up and configure the first transect of weather stations, which consists of five weather stations stretching from the coast along the Rio Loa valley to the Andes.

Scientific Field Work with Universidad Catolica del Norte (UCN – Antofagasta) and University of Cologne

During the 10-15 of September, a small group of geologists from Chile and Germany, represented by Prof. Eduardo Campos, Prof. Rodrigo Riquelme, Sebastian Muñoz (all UCN) and Prof. Tibor Dunai and Benedikt Ritter (UoC) had a first collaborative field work around El Salvador. The main objective of this short fieldwork was to investigate the geological and geomorphological landscape evolution around El Salvador.

Start Drilling PAG

Starting on Wednesday the 11th of October scientist from cluster project A02 (Volker Wennrich, Damian Lopez, Alicia Medialdea Utande, Julia Diederich, Emma Fernandez-Galego, Ascelina Hasberg) started their drilling of the clay pan south of the Rio Loa with the Chilean drilling company Superex.

Two data grants approved for Z2

Two grants were approved for the Z2 project, which is very much appreciated. The first grant is the TanDEM-X Global DEM for the whole study area by the TanDEM-X Science Team. This very accurate digital elevation model will give us the opportunity to derive geomorphometric data for many applications within the CRC, such as catchment analysis, landform classifications and drainage system analysis.

Fieldwork 2017 CRC 1211 – The workshop aftermath

Mostly all groups within the CRC 1211 used their stay after the kick-off workshop for their field work. More than 12 groups with in total more than 60 scientists sampled, measured and discussed in the field their research, met other groups in the field for in-situ discussion and sampling for cluster comprehensive collaboration and interactions within the CRC and with local scientist and experts.

CRC 1211 Kick-off Workshop, Hornitos (Chile) 13-14.03.2017

In March 2017, the first kick-off workshop of the CRC1211 “Earth Evolution at the Dry Limit” took place at Hornitos, Chile. Short talks given by researchers from Germany of each cluster and especially from our Chilean colleagues about famous research in our focus areas provided insights into recent research, ongoing/starting projects and activities achieved since the start of the CRC1211.

Introduction Field Campaign – 05.03-12.03.2017

In March 2017, a mixed group of 36 researchers from all CRC1211 projects (Biology, Geophysics, Meteorology, Geography, Geology) participate an 8-day introduction field campaign guided by Prof. Tibor Dunai, Benedikt Ritter and Dr. Damian Lopez. The group, with many young researchers (PhD students, PostDocs) visited on their trip all three focus areas of the CRC1211 to gain the big picture of our new Collaborative Research Centre.
