Split workshop: Numerical modelling

Fabian, Juan and Li with Odd Helge Otterå

Numerical modelling of climate and the oceans is a complex field, and making linkages between outputs from multiple disparate models and the data we have been working up during ARAMACC is by no means straightforward.  Where the models are similar to our data, what does that mean?  How can we use those similarities to test the models or to validate our data?  I hope we moved a little bit in the right direction during the modelling part of the workshop.  Difficult ideas were very well explained by our team of distinguished experts in the field:

Ivica Vilibic ́on dense water formation and overturning in the Adriatic; Paul Halloran with a very clear and well illustrated overview of numerical modelling followed by an introduction to the intricacies of biogeochemical modelling;  Odd Helge Ottera on how to deal with decadal variability in global ocean models can be used to address decadal variability; and the workshop ended with Eduardo Zorita covering global climate models, focusing on the climate of the last millennium.

We did also find time to take a look at our data, and found some very close and interesting connections between shell growth and some of the models.

ARAMACC Summer School #2 at Split, Croatia 9-13 May

In a little more than a month, we’ll be joining Melita and Ariadna in Croatia for the second ARAMACC Summer School, held at the Institute of Oceanography and Fisheries in Split.  As you’ll see from the pictures below, the Institute has found a prime situation for itself right at the end of the promontory with stunning views across the bay to the offshore islands.  Right, that’s the end of the travelogue – now skip past the pictures for what we’ll be doing.

As before, there will be two parts to this summer school, a sclero-specific part and a workshop on general skills associated with research.

The sclero-specific part this time focuses on “Sclerochronology and Numerical Modelling”; we’ll be discussing how to use sclerochronological time series as a tool for constraining and validating numerical climate models.  Trainers will be two experienced climate modellers from within ARAMACC, Eduardo Zorita from the Institute of Coastal Research and Odd Helge Otterå from the Bjerknes Centre for Climate Research in Bergen.  We will also welcome as guest trainers Paul Halloran from University of Exeter (Paul is the supervisor of Sarah Holmes who you met at NIOZ) and Ivica Vilibić, a physical oceanography expert who is based at IOF.

Our general workshop is about “Dissemination, Communication and Public Outreach”.  This aspect is increasingly important with the plethora of communication tools now available, and communication of science has moved a long way from the old model, with publication of results in blogs and open access journals making publication a much more fluid and interactive process than it used to be.

We’ll discuss the wide range of media that are now available for communication of science, presentation of science at outreach events, presentations to general non-specialist audiences and the importance of ensuring public access to data as soon as possible after publication.  Trainers from within ARAMACC will include our host Melita Peharda, James Scourse with his famous presentation on the various Ming controversies, Michael Carroll from Akvaplan-niva, and myself (yes, really!!) on the use of social media and, I hope, Eduardo again talking about the blog he is involved with, Die Klimazwiebal.  Our guest trainer will be Ana Bedalov who organizes the annual Researchers’ Nights in Split (see 20 seconds into the clip).  In addition, Carin will be joining us from Bergen to help with all parts of the workshop.

Looking forward to another exciting week!

Cockle picking on the tidal flats

Wednesday 28th October.  Day 3: Rob Witbaard and Chris Richardson led the group in some practical fieldwork investigating variability of shellfish distribution.  We took advantage of some decent weather to step out of the classroom to a nearby tidal flat where we collected cockles along three 300 metre transects then took them back to the lab to measure them and assess the length frequency distribution along the transects.

Ready for action!

… and slowly the cockles emerge out of the primeval slime

Cockle density plot

We even got some results. Density increased strongly towards low water, but there was a sudden cutoff at the edge of the intertidal zone, perhaps because the sediment became more sandy.

 

 

 

 

 

 

 

 

Cooked cockles

But in the end you just have to cook your fieldwork ….

Welcome to the Texel workshop

The next ARAMACC training event isn’t just a workshop.  It isn’t even a double workshop.  This time we are offering us a TRIPLE workshop featuring “Ecology of long-lived bivalves”, “Attracting funding” and “Introduction to R”.  With Rob Witbaard leading, this will take place at the world-famous Netherlands Institute of Sea Research (NIOZ) on the breezy and bracing North Sea resort island of Texel.  With this workshop happening in the last week of October, it could well be exceptionally breezy!

The workshop takes us from the welcome dinner on Sunday 25th through to Friday 30th October – or the following Monday for those who are braving the optional “R” workshop: the full schedule is here.

The workshops will feature some exciting and distinguished guests:

40f31b1eea426b60618702ea81201331Dr Bryan Black from University of Texas at Austin, dendrochronologist, sclerochronologist and proven expert in the integration of ecological variables to build multicentennial climate reconstructions.  Bryan will be introducing us to the use of multivariate analysis in ecology and leading an exercise in the application of multivariate methods to existing datasets.

 

 

DavidReynolds

Dr David Reynolds from the School of Earth and Ocean Sciences at Cardiff, who is currently aiming to publish the first 1,000-year annually resolved marine temperature record and who has just obtained funding from NERC for a pan-Atlantic sclerochronology project (CLAM – Climate of the LAst Millennium).  David will be contributing to the grant capture workshop.

 

img_2647-lavaleyeDr Marc Lavaleye, a specialist in the ecology of cold water coral reefs, will give the keynote talk at the start of the workshop on Monday.

 

 

 

 

In addition some of the ARAMACC regulars will be offering their expertise, with Julian introducing us to taxonomy and bivalve identification (useful as I suspect some of us can only identify about two species), while Chris, Paul and Rob will describe their experiences obtaining – or more often failiong to obtain – grant funding.  We’ll also – I hope (weather permitting) – get out of the classroom, when Rob takes us to sample Cerastoderma on the tidal flat.
