3rd German "dusty day"

For the third time, our Leipzig colleagues organised the "Staubtag" at the Leipniz Institute for Tropospheric Research. One day in which a lot of dusty disciplines get together to present their latest results. Here you see Michèlle presenting her latest findings on particle-size trends in our sediment traps. Laura and Jan-Berend presented their work on posters.

Welcome home, Carmen!

A month after it was packed in a container in Brazil, Buoy Carmen once again crossed the Atlantic Ocean and arrived safely back at NIOZ today. We can now do some cleaning and maintenance on the buoy, before it will be deployed off Cape Blanc again next year.

JAMSTEC: an inspiring place to work at!

Jan-Berend received a JSPS grant to work at JAMSTEC in Yokosuka and to scan some ODP cores at the Kochi Core Center.
The cores that will be scanned have registered Australian dust from the Pliocene to present on two sides of the continent.

JAMSTEC is a really inspiring place as the ships are literally on the doorstep:

Retrieving buoy Carmen in Recife, Brazil

Buoy Carmen had "escaped" from her position off Cape Blanc, Mauritania and we were very lucky that the FS Meteor was around to help. Dr. Marcus Dengler and his international team of scientists were so kind to sacrifice some time from their research program to come to the rescue. Master Jan Schubert and his crew managed to find and recover buoy Carmen and bring her to Recife, Brazil. We went to pick her up, retrieve the samples and data that had been collected since April this year, dismantle the buoy and stuff everything into a container for transport to the Netherlands. Everything worked out fine; we could even unscrew all the nuts and bolts that had been suffering from heat and salt for three years!

Buoy Carmen on tour

Buoy Carmen, which we had deployed off Cape Blanc just outside the EEZ of Mauritania last April, had decided to take a tour. Since a few weeks she was drifting freely through the Atlantic Ocean: not good. Fortunately, FS Meteor was in the immediate vicinity and we found chief scientist Marcus Dengler (GEOMAR Kiel) and master Jan Schubert willing and able to come to our rescue and recover the buoy.

A great THANK YOU to both Marcus and Jan and their scientific and shipboard crews!!!

HOVO visits NIOZ

Today (July 6, 2016) a group of people from HOVO (Hoger Onderwijs Voor Ouderen - Higher Education for Elderly) visited NIOZ with Prof. Bert Boekschoten, to learn more about our dusty research and the institute. Laura gave an interesting talk about our research, followed by a tour of our workshop and labs.

Many thanks also to Jan Boon and Edwin Keijzer!

Kenniscafé

The evening in the "Kenniscafe" was great fun!

It has been registered completely, please click the picture for a link to the vimeo site where you can view it.

Kenniscafé

 

(Dutch event)

Op maandag 20 juni organiseren De Volkskrant, KNAW, NEMO Science Center en De Balie een avond in het kenniscafé: Diep in de Zee. Het thema van de avond is duidelijk en hierover worden een aantal mensen geinterviewd. De avond is live te volgen via: www.debalie.nl

 

DUST2016

From 13-17 June the meeting DUST2016 was held in Castellaneta Marina, Italy. A meeting we could obviously not miss!

Here you see Laura present the state-of-the-art of her work.

 

Mooring M4 recovered successfully by Bremer colleagues!!

During our last expedition o/b RRS James Cook, we could not recover mooring M4 due to bad weather.

Fortunately, our colleagues from MPI-Bremen and MARUM-Bremen offered to recover it for us during their expedition M126 o/b FS Meteor just north of our mooring site.

We just heard the exciting news that they indeed managed to recover our mooring, despite rough weather. What's more; the mooring contains a beautiful sequence of events covered by the two traps at 1200m and 3500m depth.

Last month we already recovered the filters from dust-collecting buoy "Laura" at this site so that for the first time we can now compare Saharan dust blowing through the air with material (dust and marine organic matter) sinking through the water column.

A big THANK YOU to chief scientist Nicole Dubilier and Master and crew of RV Meteor!!!

ACPD paper out!

A first for Michelle; her manuscript was accepted by ACP as --initially-- a discussion paper.

Already, the first questions have been posted, let's hope for an interesting and fruitful discussion!

 

 

Research Cruise JC134

In March-April 2016 a large team of scientists from NIOZ and affiliated institutes boarded the Royal Research Ship James Cook. We've been keeping a blog, which you can find at: www.nioz.nl/jc134-blog.

Research Cruise MSM48

In November 2015 some people from our dust team participated in cruise MSM48 on board the German Research Vessel Maria S. Merian. We've kept a blog on this cruise, which you can find at: www.nioz.nl/msm48-blog.

Michèlle visits RSMAS

In October 2015, Michèlle is staying at the Rosenstiel School of Marine and Atmospheric Science in Miami, USA, to work with Dr. Ali Pourmand and Prof. Joe Prospero. Using the isotopes of trace metals like Sr, Nd, and Hf, she tries to trace back the dust we collected over and in the ocean towards their source(s). In addition, using the particle-size distributions of collected dust, she tries to line up our dust samples with the daily samples that Joe Prospero has been collecting since the late 1960's (and ongoing!) on Barbados.


Preparing another cruise

In November, we'll visit buoy Carmen off Mauritania in a joint cruise with MARUM-Bremen colleagues onboard the German Research Vessel MS Merian. To this end, spare parts and equipment will be sent from Bremen towards the ship, which will depart from the Azores. Here you see the NIOZ mini-van packed with gear.


Mediterranean dust

A large share of Saharan dust ends up in the Mediterranean.

So, we thought it's a good idea to monitor and collect that stuff, so that we can compare it to the material that is exported from Africa towards the Caribbean!

Right now, RV Pelagia is on a transit between Malaga and Istanbul and on their way they'll service our Mediterranean dust trap. You can follow Rick Hennekam's adventures through the NIOZ tumblr blog


Planning ahead

Preparations are already being made for upcoming cruises such as the transatlantic cruise early next year onboard RRS James Cook.


Even during summer holidays....

Even during summer holidays we encounter dust, although not necessarily from deserts....


EGU 2015 Outstanding Student Poster prize for Michèlle

The jury of the Outstanding Student Poster committee awarded a prize to Michèlle van der Does for the poster she presented at the European Geosciences Union meeting last April. Well done Michèlle!


Dusty lectures (in Dutch)

Starting 20 May 2015, you can follow lectures on dust here.

A series of five dusty lectures was recorded, and in these five lectures Jan-Berend tries to explain why he is so fascinated about dust.

All lecures are in Dutch.


Dusty scholars in Korea

In May 2015 Jan-Berend went to Daejeon, South Korea, to teach on mineral dust in KIGAM's special lecture series. Here you see the participants who joined the course.


Transatlantic cruise 64PE395

In January 2015 we've set sail again on board RV Pelagia to service our transatlantic array of instruments and re-deploy them.

Through this blog  we tried to keep you informed about our adventures at sea.


On this page we present our dusty work that is being carried out at NIOZ in several projects:

1) TRAFFIC: Transatlantic fluxes of Saharan dust and ocean - climate impacts.
[funded by NWO]

2) DUSTTRAFFIC: Transatlantic fluxes of Saharan dust - changing climate through fertilising the Ocean?
[funded by ERC]

3) Nutritive contribution of desert dust in the Arabian Gulf to the microbial productivity of the Arabian Gulf marine ecosystem: sources, fluxes and possible pathways.
[funded by QNRF]

4) Aerosol-induced feedbacks in the climate system in the Earth system.
[funded by DFG through MARUM]



Dusty scientists meet on Barbados

After the cruise early 2015, which took us to the Island of Barbados, we just HAD to visit the dust-monitoring station that Joe Prospero had set up in the 1960's. This station is considered a true dust Mecca!

We were very fortunate to meet a local scientist, who has been studying Saharan dust for a long time: Edmund Blades. Here you see Edmund and Jan-Berend at the dust station near the lighthouse of ragged point.
