  • NORUS Workshop II, Cal Poly: IVER Progress
    movements along an ice edge in the Arctic As an intro to the Remus presentation Jørgen Bergen gave some short input of the scientific relevance of using the Remus in futureArctic missions There are two aspect to focus on measuring diel vertical migration DVM and affect of ice on biological communities After a really nice sushi dinner at the Yanagi s Zoë Wood and Daniel Medina presented software for 3D

  • NORUS Workshop II, Cal Poly: Monday, November 23
    its platform is made of steel and has holes in the floor so that the water could filter out After the safety briefing we all gathered around t he SLOCUM glider RU16 and opened it up to ch ec k out the hardware The glider has a bladder that fills with air in the tail cone to keep the tail out of the water This makes communicating with satel lites easier The front of the glider also known as the head cone can be f illed with water so that it sinks In the middle there are batteries and other hardware We learned a lot about ballasting the glider to make it sink without a roll or pitch at a 26 degree angle Some of the Norwegian students interrupted the lecture to give us their cu sto m made coffee mugs Using what we learne d we put the glider in a water tank to see how it looked The tail was slightly heavier than the front but not significant for the launch Then we all ate lunch in the sun behind the marine lab building The meal was delicious and the sun was relaxing which was perfect for cold adapted students from Norway We also got to see some big whales in the horizon Basically it was a perfect lunch setting After lunch we learned a lot about how to program the gliders and how to prepare them for missions We planned a mission which you all can follow on Google earth We then went to dinner at the Steamers of Pismo We had some nice expensive white wine and a big pleasant meal After the meal we headed back to the Avila beach Marine Institute for a late evening lecture from Chris Clark about autonomous control and state

    group concluded the hike by enjoying a beautiful sunset and some nice group pictures Starving from the strenuous stroll but excited to have survived the perils of poison oak and obnoxious otters we congregated yet again at the customs house for a feast After having over eaten on american portions we returned to the science center for John s teaser talk on gliders and their potential Prof Moline explaining the perils of poison oak it will get you and it will kill you Here is what we heard Gliders today are no longer a pipe dream but are actually in use all over the globe making science as they go Gliders vary their buoyancy and produce forward movement by flying up or down using their wings to push water behind them They have no need for propellers which means reduced energy consumption and mission times of several months With this kind of mission lengths biofouling becomes an issue as a naked glider is like a virgin land on which hydroids lepas duckbill shells barnacles and algae immediately starts settling whereever they can get a foothold Coating with Teflon and jumping between water masses of sharp temperature gradients represents a couple of the solutions but neither is simple and straightforward Models have normally been driven by remotely sensed products like satellite and Codar radar products Unlike these technologies gliders produce data from beneath the surface as well literally providing in depth input data for your model Shipboard surveys can be very thorough and accurate but are expensive while gliders and AUVs are cheap in comparison In your waters of interest the Webb Slocum is the only glider able to operate in a coastal setting less than 200 meters deep The Seaglider and Spray glider have longer deflection times and thus need

  • NORUS Workshop II, Cal Poly: Overview for the week
    16 s trip around California and got out on the Zodiac to deploy After deployment Cal Poly participants informed us about the IVER 2 a propelled AUV that uses sonar to monitor the coast Although the IVER2 run short term missions it is very efficient and is low cost Scott Layton Cal Poly Wednesday 25 On Wednesday Mark Moline educated us on the REMUS another AUV It is like the IVER2 because it runs short term missions however it carries more sensors and has a GPS system The students had a short competition to write code for a mission that was then carried out a little ways off the pier We then learned about crawlers which are small tank like sampler that crawl along the bottom of a basin and take samples and ROVs which are small tethered and remotely controlled robots Thursday 26 On Thursday we celebrated Thanksgiving the California way by learning how to surf and having a nice traditional thanksgiving dinner including turkey stuffing cranberry sauce and mashed potatoes at a country club Friday 27 Friday we worked as a group on the lay out of the NORUS website www norus science com and discussed future workshops

    thing to do in surfing I remember thinking how it really didn t look that difficult until we all tried standing up in the water I never thought that something that looked so easy could be so difficult Everyone ended up tasting enough salt water by the end of the session but it was a great experience for all of us I still think I have the taste of salt water in my mouth Dr Chris Clark was in the more a dvanced section in the water as he looked like a professional next to all of us After we all grabbed a quick lunch after the surf session we headed back to Avila and rested for a bit before meeting up for a fun Thanksgiving dinner generously prepared for us by one of Mark s friends Dinner was excellent and the turkey was great Mark brought plenty of wines for all of us to enjoy during dinner and Erlend being Erlend ordered a few more for the table We ended the dinner with some really good desserts including the traditional pumpkin pie and another dessert filled with chocolate tastiness which had everyone at the table sampling Overall it was
