CCU's 2015 Hurricane Forecast on the Mark

As shown in the table below, the HUrricane Genesis & Outlook (HUGO) forecast was successful in range in every category but the named storms (off by 1) with some exact hits. For the 2016 hurricane season, the HUGO team plans to further refine its Outlook and Land-Fall forecast capabilities.

Radiography Sample Preparation

We prepared a core that has excellent internal sediment structures with lamination, i.e., the preserved products of rapid environmental changes in the past. This was maybe the only core that had very little bioturbation. Bioturbation occurs when organisms disturb the original sediment structures with their burrows. This process destroys the natural lamination within. The core was taken just in front of the Guadalquivir River mouth in 22 m of water.

A Brief Overview of a Mud Belt Core

A typical mud depocenter core is composed of very fine brown/grey pretty homogenous mud that has collected on a continental shelf over time. In the northern Gulf of Cadiz, the very gently sloping shelf allows for sediment accumulation to occur in areas where ocean bottom currents are minimal. Most of the cores we collected during the CADISED cruise on RV Poseidon in March 2015 were composed of this very fine mud, sometimes with centimeter sized layers of siltier mud. Often bivalves, gastropods and worm tubes could also be found within.

CADISED Project Visit at MARUM in Germany

Continental shelves under fluvial influence commonly host locally confined mud depocenters which accumulate on the otherwise sandy and rocky shelves. The sediment successions of such depocenter contain highly valuable environmental information on past oceanographic and climatic variability: they represent the most distal marine sink for continent-derived material as well as most directly affected deposit in terms of shallow-water bottom currents.

Aftermath of the Sampling Party

With the aim to decide the next steps of core analysis, today we compared the cores, discuss possible transgressive sequences, and where the base of the mud depocenter is located in the Guadalquivir area of the Gulf of Cadiz. 

A short trip to Hamburg

Saturday, I took the day to explore Hamburg, the second largest city in Germany. The people from there call their city “my pearl” and “the gate to the world”. Train traveling has been a great experience so far.  Everything is almost exactly on time!  The train ride to Hamburg from Bremen took only a little over and hour and a half.  During my adventure, I met people biking Germany from Sydney, Australia.  One of them was actually born in Pittsburgh, PA which is only an hour and a half’s drive from my hometown. SMALL WORLD!
