Mesozooplankton size data from the fjord branch Kapisigdlit located in the Godthaabsfjord system, West Greenland
No full textSampling was conducted from March 24 to August 5 2010, in the fjord branch Kapisigdlit located in the inner part of the Godthåbsfjord system, West Greenland. The vessel "Lille Masik" was used during all cruises except on June 17-18 where sampling was done from RV Dana (National Institute for Aquatic Resources, Denmark). A total of 15 cruises (of 1-2 days duration) 7-10 days apart was carried out along a transect composed of 6 stations (St.), spanning the length of the 26 km long fjord branch. St. 1 was located at the mouth of the fjord branch and St. 6 was located at the end of the fjord branch, in the middle of a shallower inner creek . St. 1-4 was covering deeper parts of the fjord, and St. 5 was located on the slope leading up to the shallow inner creek. Mesozooplankton was sampled by vertical net tows using a Hydrobios Multinet (type Mini) equipped with a flow meter and 50 µm mesh nets or a WP-2 net 50 µm mesh size equipped with a non-filtering cod-end. Sampling was conducted at various times of day at the different stations. The nets were hauled with a speed of 0.2-0.3 m s**-1 from 100, 75 and 50 m depth to the surface at St. 2 + 4, 5 and 6, respectively. The content was immediately preserved in buffered formalin (4% final concentration). All samples were analyzed in the Plankton sorting and identification center in Szczecin (www.nmfri.gdynia.pl). Samples containing high numbers of zooplankton were split into subsamples. All copepods and other zooplankton were identified down to lowest possible taxonomic level (approx. 400 per sample), length measured and counted. Copepods were sorted into development stages (nauplii stage 1 - copepodite stage 6) using morphological features and sizes, and up to 10 individuals of each stage was length measure
Mesozooplankton size data from Disko Bay, West Greenland, 2008
No full textThe study site was located in the Disko Bay off Qeqertarsuaq, western Greenland. Due to land-connected sea ice coverage during winter, 2 sampling sites were combined. At the first site in winter (21 February to 23 March 2008), sampling was conducted through a hole in the ice at ca. 65 to 160 m depth approximately 0.5 nautical mile (n mile) south of Qeqertarsuaq (69° 14' N, 53° 29' W). In spring and summer (9 April to 18 July), sampling was done at a monitoring station 1 n mile south from Qeqertarsuaq (69° 14' N, 53° 23' W) at 300 m depth. Sampling was carried out between 10:00 and 17:00 h. During sampling from the ice, mesozooplankton was collected using a modified WP-2 net (45 µm) equipped with a closing mechanism (Hydrobios). Samples were collected in 3 depth strata (0-50, 50-100, and 100-150 m). During ship-based sampling, mesozooplankton was collected with a multinet (50 µm) equipped with a flow meter (Multinet, Hydrobios type midi), and 2 additional depth strata (150-200m and 200-250 m) were included. In addition to the seasonal study one diurnal investigation with sampling every 6 h was conducted from 29 April at 12:00 h to 30 April 30 at 12:00 h. Samples were immediately preserved in buffered formalin (5% final concentration) for later analyses. Biomass values of the different copepod species were calculated based on measurements of prosome length, and length/weight relationships. Two regressions for Calanus spp. were established for biomass calculations: one applicable prior to and during the phytoplankton bloom until 4 May, and another from 9 May onward

Tireless in His Service: Rasmus Andersen, Pastor and Author 1878-1924
No full textOf the four founders of the Danish Lutheran Church in America in 1872, the one concerning whom the most information exists is Rasmus Andersen. Yet it has been my observation that comparatively little is known about him. A reason for this is that, to my knowledge, no comprehensive biography exists, and there is almost nothing available in the English language. Most of the material that does exist is to be found in the Danes World Wide Archives ( Udvandrerarkivet ) in Aalborg, Denmark. According to Birgit Flemming Larsen, who oversees that archive, the Andersen collection is the largest at the Aalborg archive. It consists of 104 archival boxes, filled with books, letters, diaries, memoirs, ministerial records, copies of letters sent, unpublished manuscripts and much more. The Danes World Wide Archives constitutes a treasure trove for the researcher who is interested in Rasmus Andersen
Early life of inshore fishes in Greenland:With emphasis on Atlantic cod (Gadus morhua)
No full textFiskebestande står over for en række af udfordringer for at gennemføre en succesfuld reproduktion. Gydningen skal finde sted i områder hvor deres æg og larver kan blive tilbageholdt under gunstige forhold, og der skal være et hensigtsmæssigt sammenfald i tid og rum mellem larverne og deres bytte for at sikre en hurtig vækst og undgå sult. Indenskærs områder kan tilbyde sådanne forhold da de ofteer beskyttet fra havstrømme, og endvidere kan fungere som en fysisk barriere der kan formindske spredningen af æg og larver. På trods af at indenskærs gydeområder af fx torsk (Gadus morhua) er almindelige i mange Norske, Canadiske og Grønlandske fjorde, mangler der viden om disse bestandes tidlige livsfaser og deres afhængighed af de fysisk-biologiske mekanismer, der kan påvirke vækst og overlevelse. For at give bedre forståelse for de processer der er vigtige succesfuld gennemførsel af de tidlige livsstadier af fisk, udførte jeg et sæsonstudie på en Vestgrønlandsk population af indenskærs torsk. Jeg undersøgte her fordelingen, udviklingen og dødeligheden hos æg og larver i relation til de fysiske forhold og tilgængeligheden af bytte. Gydningen var hos denne population begrænset tilet lavvandet indenskærs område i den inderste del af fjordgrenen Kapisigdlit i Godthåbsfjord-systemet. Karakteristisk for dette område var en højere temperatur i den øvre del af vandsøjlen, som forøgede udviklingshastigheden af æg. Dødeligheden var lav i gydningsområdet, og spredningen af æg derfra var begrænset. Senere på sæsonen da isen brød op i en flodder udmunder i fjorden, skete der en forøget spredning af de nu noget ældre larver. Gennem undersøgelsesperioden fandt jeg markante tidslige og rumlige forskelle i sammensætningen af dyreplanktonet. Fordelingen af larver var generelt sammenfaldende med fordelingen af deres fortrukne bytte. Selvom der ikke kunne påvises en direkte sammenhæng mellem tilgængeligheden af byttedyr og larvernes vækst, viste undersøgelsen at der var en signifikant forøgelse i væksten hos larver som drev ud fra gydeområdet. Dette var på trods af at temperaturenvar lavere uden for gydeområdet, hvilket indikerer atlarvernes vækst i højere grad var påvirket af tilgængelighed af byttedyr. En relativ lav dødelighed for æg og larver samt en høj vækst hos disse larver sammenlignet med larver fra andre studier, indikerer at forholdene i denne fjord er særligt gunstige for de tidlige livsstadier af torsk. Forholdene kan resultere i en stærk rekruttering, hvilket kan være det væsentligste grundlag for den store gydebestand af torsk som findes i Kapisigdlit. Da forskelige arter af fisk benytter forskellige gydestrategier, som er tilpasset til forskellige fysiske og biologiske forhold, vil man forvente at artssammensætningen af larvesamfundet vil ændre sig i forhold til fysisk-biologiske gradienter. Jeg undersøgte derfor fordelingen og artssammensætningen af fiskelarver i relation til ændringer i hydrografi og tilgængelighed af byttedyr over et område med store forskelle i disse forhold. Undersøgelsen blev udført langs VestgrønlandsGodthåbsfjord-system og udenskærs Fyllas Banke, hvor der sker store ændringer i artssammensætningen af dyreplanktonnet fra område til område. Jeg fandt signifikante forskelle i artssammensætningen af fiskelarvesamfundet, som var koblet til specifikke hydrografiske forhold samt tilgængeligheden af fortrukne byttedyr. Generelt blev der fundet få arter af fiskelarver tæt på gletsjeren, hvilket viser atdet var et dårligt habitat for de fleste arter, mens habitater ved indgangen og i andre grene af fjorden var forholdsvist artsrige. Vestgrønland vil opleve store miljøændringer i fremtiden, bl.a. ved ændringer i vindforholdene, i indstrømning af vand fra Atlanten, ved temperaturforøgelser, øget afsmeltning af indlandsisen samt afstrømning fra land. Denne afhandling pointerer, at disse fremtidige ændringer ved deres påvirkning af tidspunktet for, ferskvandsafstrømningen, og derved cirkulationen i fjordsystemer, kan fåstore konsekvenser for opvæksten i de tidlige livsstadier af fisk og dermed også den fremtidige artssammensætning af fiskebestandene i området.During their early life stages, the fishes face a range of challenges. To sustain the development of the pelagic eggs and larvae spawning needs to occur where the offspring is retained in optimal environmental conditions. The larvae rely on a spatial and temporal match to their prey in order to ensure fast growthand avoid starvation. Inshore areas may provide such favorable conditions, as these are sheltered from offshore currents and act as physical barriers that restrict dispersal and drift of eggs and larvae. Even though inshore spawning grounds of e.g. Atlantic cod (Gadus morhua) has been reported from numerous fjords in Norway, Canada and Greenland, very little is known about their early life history and the physical-biological mechanisms impacting their survival in such inshore areas. To better understand the processes of importance to the early life success of fish, I carried out a seasonal study on a West Greenlandic inshore population of Atlantic cod. I followed the distribution, development and mortality of eggs and larvae in relation to the physical conditions and the prey availability. The spawning of this population of cod was restricted to a shallow inshore area located at the innermost part of the fjord branch Kapisigdlit, in the Godthåbsfjord system. This shallow area was characterized by elevated temperatureswithin the upper part of the water column, which increased the development rate of the pelagic eggs. The mortality in the immediate spawning area was low and egg dispersal from the area was limited. Later, the seasonal breakup of ice in a connecting river resulted in an increased freshwater outflow, then enhancing the dispersal of the older larvae. Throughout the study, marked spatial and temporal differences in the zooplankton community composition were observed. The distribution of larvae generally overlapped the distribution of their preferred prey. Although no direct relationship could be found between prey availability and cod larval growth, the otolith growth rate was significantly improved in larvae that dispersing away from the spawning area. This was despite lower temperatures, suggesting that prey availability had some influence on the growth pattern. The relatively low mortality rates of eggs and larvae,and high larval growth rates compared to other studies, indicate that this fjord affords especially favorable conditions for the early life stages of cod. These conditions may result in a strong recruitment, which again might be the background of the relatively high cod spawning stock biomass found in Kapisigdlit. Since different species of fish may vary in their spawning strategies and adaptations to physical and biological conditions, the larval assemblages in inshore areas with variable physical and biological characteristics are likely to be strongly structured. Therefore, I assessed the distributional patterns of larval fish assemblages comparing distributions to the variability in hydrography and prey availability. This was carried out across the West Greenlandic Godthåbsfjord system and the offshore Fyllas Bank, which encompass different oceanographic regimes, and which harbor different zooplanktoncommunities in specific regions. Significantly different patterns of distribution were shown for the fish larvae and these appeared linked to the specific hydrographical conditions and the availability of preferred prey. Generally few larvae were found close to the glacier suggesting that this was a poor habitat for most species, while habitats at the entrance and in other branches of the fjord was relatively rich in species of fish larvae. With changes in wind regimes, relative inflowof Atlantic water, temperature increase, glacial melting and runoff from land, the environment off West Greenland will undergo significant changes in the future. This thesis points out that in fjord systems, where such processes might change the timing and magnitude of freshwater outflow and circulation patterns the distributional patterns and life of the early life stages of fishes can be markedly affected

Lisäksi opasta muokataan, mikäli yrityksen toimintatavat ja työsuoritteet muuttuvat.The purpose of this thesis is an orientation guide for the new employees of the employer company Pirkanmaan Saneerauspalvelu Ltd. The company has not previously had an orientation guide for its employees, so the orientation of new employees has been implemented by more experienced workers in the workplace. In addition, during the orientation an induction tour has been held in the hall, where the supervisors have shown the locations of different materials, briefly told general things about the company and which tasks belong to whom. The objective of this thesis is to make it easier and clearer for the new employees to start working. In addition, the aim is to reduce the burden on supervisors as well as more experienced employees when orienting a new employee.
In addition to orientation, this thesis deals with construction occupational safety, work processes and the materials used. The work also examines the safe use of machines and equipment used to work, ERP system called Easoft and issues regarding quality assurance. In the end potential follow-ups are pondered. To create this orientation guide information was collected from various written sources. In addition, professionals working in the company has been interviewed and the own experiences of the author of this thesis on the construction industry has been collected.
In the future, the orientation guide will be distributed to new employees when writing an employment contract and also for new agency workers. The new employees as well as the agency workers should read the orientation guide before starting the actual work.
In the future, the orientation guide can be modified by the management based on feedback from employees. In addition, the guide will be modified according to the changes of the company's policies and processes
Bibliometric author evaluation through linear regression on the coauthor network
No full textThe rising trend of coauthored academic works obscures the credit assignment that is the basis for decisions of funding and career advancements. In this paper, a simple model based on the assumption of an unvarying “author ability” is introduced. With this assumption, the weight of author contributions to a body of coauthored work can be statistically estimated. The method is tested on a set of some more than five-hundred authors in a coauthor network from the CiteSeerX database. The ranking obtained agrees fairly well with that given by total fractional citation counts for an author, but noticeable differences exist
Rasmus Sorensen and Danish Emigration, 1847-1863
No full textProbably no individual played a more seminal role in the limited Danish emigration to North America before and during the Civil War than Rasmus Sorensen. From the late 1840s until the early 1860s this author, educator, politician, and social reformer led three groups of his countrymen to Wisconsin and, through numerous booklets, speeches, and letters encouraged others to settle elsewhere in the United States and Canada. Yet Sorensen has generally been little more than a supernumerary in the historiography of this transatlantic migration. Its pioneering historian, Peter Sorensen Vig, devoted twelve pages to him in his mammoth compendium, a dozen more than John Bille allowed him in his disjoint narrative of 1896. Arne Hall Jensen described Sorensen \u27s life in two paragraphs in 1937, giving various biographical details without interpreting their significance. There is little to indicate that the recent revival of interest in the Danish-American field will reverse this long tradition of neglect. In his monumental study of emigration from Denmark, Kristian Hvidt relates his activities in a scant paragraph, perhaps justifiably, because Sorensen \u27s lifespan fell completely outside Hvidt\u27s chronological framework
