This is a report from the first experimental year of the project ‘VELVET GREEN - Winter hardiness and management of velvet bentgrass (Agrostis canina) on putting greens in northern environments’. The report is divided into three parts, the first giving results from evaluation of winter hardiness of velvet bentgrass under controlled conditions, the second describing experimental layout and preliminary results from two field trials with fertilizer levels, thatch control methods and topdressing levels; and the third describing experimental layout and preliminary results from a lysimeter study on irrigation stategies for velvet bentgrass on greens varying in rootzone composition.

Forsøket var en delundersøkelse i dokumentasjonen av et nytt avløpsfritt rensekonsept for svartvann fra toalett. På campus til UMB på Ås i Norge ble det under to sommerperioder, to vintrer, en høst og en vårperiode målt fordampning av vann fra et barkbasseng plassert under en betongrampe med to åpne sidevegger. Under sommerforhold ble det målt en fordampning på fra 0,9 til 1,1 kg vann/m2 døgn når vannspeilet lå fra 0 til 10 cm under toppen av barklaget. Når vannspeilet lå dypere sank fordampningen til 0,2 og 0,13 kg vann/m2 døgn. Under vinterforhold ble fordampningen målt til 0,25 kg vann/m2 døgn. Fordampningen på vinterstid skjedde hovedsakelig i mildværsperioder hvor deler av vannet nær overflaten smeltet. For å øke fordampningen bør en større del av barken i umettet sone komme i kontakt med gjennomstrømmende luft ved at overflaten økes ved bruk av barkranker, en aerodynamisk utforming av luftstrømningskanalen over barkbassenget, utformingen av bassenget og eventuell bruk av vifter. Varmekabler kan brukes under vinterforhold for å redusere isdannelse i barkbassenget.

Oil transport from the Russian Arctic. Is the Barents Sea environment at risk? The volumes of oil being transported by sea from the Russian Arctic along the coast of Northern Norway were insignificant before 2002. In 2006, however, a total of 10 million tons of Russian export oil and oil products were shipped from Russia, on ships that sailed along the coast of Norway. The annual oil exports from the Russian Arctic regions via this Northern route may reach a total of about 50-80 million tons in the next decade. About 50 million tons of crude oil and oil products are estimated to be delivered by railway to the Murmansk ports in the Barents Sea, and to Kandalaksha and Arkhangelsk in the White Sea. Furthermore, up to 20 million tons of oil will be produced in the northern oil fields in the Nenets Autonomous Region and in the Pechora Sea. The terminals in the Kara Sea, can load 2-3 million tons of crude a year. The Barents Sea is one of the most productive oceans worldwide. Few other places on our planet give home to the same amount of breeding seabirds. Here, more than 20 million seabirds from 40 species breed in 1.600 colonies every year. Many of the seabird populations are of mixed Russian-Norwegian origin. In case of an oil spill, the actual amount of oil spilled is not necessarily decisive for the effects on sea bird colonies. The Stylis had a relatively small spill " but 45.000 seabirds were killed. The estimated mortality of the accident was, however, 200.000-300.000 birds. The Amoco Cadiz spilled 223.000 tons of crude oil, but killed 5.000 seabirds. Methods for evaluation of effects on and treatment of birds that have been involved in an oil spill do exist. After the Prestige accident outside Spain, 23.428 seabirds were collected. 5.776 survived. About 1.000 seabirds were released back to nature at a cost of approximately NOK 23.000 (USD 4.100 or EUR 3.000) per bird. The increased development of offshore petroleum fields and increasing sea transport of hydrocarbon products are bound to have a negative effect on the environment. Oil and gas industry developments in the Barents Sea, fisheries, pollution and climate change are the most important treats to the environment in our time. When carrying out impact assessments of activities connected to petroleum activities in this area, one of these factors cannot be evaluated separately, without taking all the other risks into account.
