A study was carried out to assess primary production and associated export flux in the coastal waters of the western Antarctic Peninsula at an oceanographic time-series site. New, i.e., exportable, primary production in the upper water-column was estimated in two ways; by nutrient deficit measurements, and by primary production rate measurements using separate 14C-labelled radioisotope and 15N-labelled stable isotope uptake incubations. The resulting average annual exportable primary production estimates at the time-series site from nutrient deficit and primary production rates were 13 and 16 mol C m−2, respectively. Regenerated primary production was measured using 15N-labelled ammonium and urea uptake, and was low throughout the sampling period. The exportable primary production measurements were compared with sediment trap flux measurements from 2 locations; the time-series site and at a site 40 km away in deeper water. Results showed ∼1% of the upper mixed layer exportable primary production was exported to traps at 200 m depth at the time-series site (total water column depth 520 m). The maximum particle flux rate to sediment traps at the deeper offshore site (total water column depth 820 m) was lower than the flux at the coastal time-series site. Flux of particulate organic carbon was similar throughout the spring–summer high flux period for both sites. Remineralisation of particulate organic matter predominantly occurred in the upper water-column (<200 m depth), with minimal remineralisation below 200 m, at both sites. This highly productive region on the Western Antarctic Peninsula is therefore best characterised as ‘high recycling, low export’.

The Spirit Of The Suwannee Music Park has seen some fairly incredible jams over the years, and the Suwannee Summer Clusterpluck was a fine addition to that hallowed tradition. The concept behind the two-day bluegrass Clusterpluck was a simple but solid one on the part of promoter Paul Levine: Gather some of the finest pickers in the land, add a proper stage and PA, and turn the musicians loose. The result was a weekend of musical mix-and-matching, with each set sporting a number of sit-ins and collaborations from the talented musicians on hand in addition to the super jam on the final night dubbed the “Summer Suwannee Clusterpluck.”Vince Herman Leads Wild 30-Minute “Midnight Rider” All-Star Jam At Clusterpluck [Video]Of course, when it comes to pulling together the right players for an event of this nature, it’s easier said than done. To make an event like Clusterpluck work, you need to find the right balance of talents and personalities, and for the final super jam, it doesn’t hurt to have someone who can act as an on-stage general to keep everyone on the same page. So when Levine was putting the event together, he knew there was only one choice to help him launch this new endeavor — the living embodiment of festival life himself, Leftover Salmon‘s Vince Herman. Herman, along with his partner-in-Salmon/crime Drew Emmitt, acted as the brain trust for the planned super jam, in addition to the duo taking on the responsibility of a set each day.The Wit And Wisdom Of Leftover Salmon’s Vince HermanGenerals need soldiers, and Clusterpluck filled out its ranks with the husband and wife duo of flat-picker guitar buzzsaw Larry Keel and his bass-playing better half Jenny Keel. Rising stars The Jon Stickley Trio brought their neo-classical, jazz-tinged bluegrass to add much-needed depth and sonic diversity to the mix as well. Outlaw bluegrass act Grandpa’s Cough Medicine, Pickled Holler, Albert Simpson and the right Reverend Jeff Mosier rounded out the stellar assortment of musical weapons at the disposal of the coming war on boredom.The various bands each took a set a day, eagerly welcoming their fellow players from the other acts for a weekend chock full of magical collaborative moments that simply can never be repeated. The off-the-cuff energy and improvisational nature of the performances made each song an adventure that was familiar but boldly retold for fresh ears. The fun didn’t even stop when the last notes rang out in the beloved Suwannee Music Hall, as the players took their musical circle out into the friendly confines of the park itself.The Spirit Of The Suwannee Music Park was founded so that bluegrass could flourish year round, and the Clusterpluck did a wonderful job of honoring that tradition. Fans of the genre and fans of music itself would do well to hope that the “Summer” in the title is an indication of a seasonal return for this first-time event. Until such an announcement comes, our own Rex Thomson has several highlights from the first iteration of the festival for you to check out below. Keep an ear out for possible follow-up events in the future, and until then, you can listen to a variety of tracks from the various acts and the best of the multi-player mayhem that closed out the weekend. It truly earned the title “Clusterpluck!” Enjoy!Grandpa’s Cough Medicine“Jam 1”“I Ain’t Got The Money To Drink No More”Larry & Jenny Keel“Ashes Of Love”The Jon Stickley Trio“Jam”Vince Herman & Drew Emmitt“Gentle On My Mind”“Melissa”Suwannee Summer Clusterpluck“Road Kill”“Black Muddy River”“How Mountain Girls Can Love”“Jam”“Louie Louie>Love Light”The combination of friends and family, great weather, and once-in-a-lifetime music made the inaugural Suwannee Summer Clusterpluck a perfect blend of love and insanity. The players had the time of their lives, and the audience was delighted to be the lucky recipients of an incredible feel-good show in The Spirit Of Suwannee Music Park. When the artists feel as at home as the fans and the smiles never fade away, you know you are exactly where the universe wants you to be.
Silverstone: In a podium dominated by Spaniards, Alex Rins of Suzuki earned his seasons second victory at the British Moto Grand Prix (GP) in a stellar finish, prevailing over Repsol Honda rider Marc Marquez and Yamaha’s Maverick Viñales.Rins knew how to wait for the right moment to get past Marquez when he had least expected it.The British Moto Grand Prix racer knew how to close all the doors on his rival but he relinquished the penultimate lap to prepare for the last one, Efe news reported.Alex Rins seized the opportunity and got past Marquez by 0.013 seconds on Sunday.“Unbelievable! I do not have words to explain,” Rins said when asked about his feelings to have won the British Moto Grand Prix.“I was so close to do a big mistake because two laps to the end, I was thinking it was the last lap. I was keeping the calm. I knew he was faster on that part of the sector but the last corner for me was unbelievable. I was much faster than him,” he added.Meanwhile, Marquez did not seem to be satisfied with the result.“Happy about the championship, but the race no. I knew Rins had a big chance. I keep pushing because my target was not the race, was the championship to take a lot of points,” Marquez said.

Creedon praised his players’ effort yesterday but highlighted the importance of some of the younger players to the Tipp team. Meanwhile along with Louth, David Power’s Wexford team was relegated to Division 4 next season. The Tipp native said his side needed that win ahead of the championship. Tipperary senior football Peter Creedon says they won’t dwell too much on their loss to Wexford yesterday in their final round League game of the National League. The Premier County suffered a three point defeat in Clonmel on a full-time score of 2-12 to 2-15. With their Division 3 status already secured, a number of Under 21 players were rested for the match-up ahead of their Munster Final against Cork this Thursday in Semple Stadium.
