Stofnvöktun Lunda 2017-2019
STOFNVÖKTUN LUNDA 2017-2019 Lokaskýrsla til Umhverfisstofnunar Árlegur stofnvöxtur lunda (λ) á Íslandi 2010-2019. Stofninn vex þegar λ > 1 og rénar þegar λ < 1, λ = 1 er sýnt með svartri láréttri línu. Veiðar eru stofnvistfræðilega ósjálfbærar þegar þegar λ < 1. Geometrískt meðaltal λ árin 2010-2019 er 0,96478, eða -2,73% fækkun á ári. Reiknuð fækkun með þessu meðaltali árabilið 2003-2019 er - 43,7%. Litir sýna þá IUCN flokka sem viðkomandi stofnvöxtur raðast á hverju ári: rauður; Í bráðri hættu – Critically Endangered; appelsínugulur; Í hættu – Endangered; gulur; Í nokkurri hættu – Vulnerable; grænn; Ekki í hættu – Least Concern. Erpur Snær Hansen 15. desember 2019 Náttúrustofa Suðurlands Stofnvöktun lunda á Íslandi 2017-2019 SAMANTEKT Lundi er algengastur og einna mest veiddur íslenskra fugla. Næstum allur lundi er nú veiddur í háf á varptíma og varð háfaveiði ríkjandi veiðiaðferð í Vestmannaeyjum um 1880 [1]. Þar hefur veiðimagn verið tengt sjávarhita frá 1880 [2]. Skiptast á hlý- og köld tímabil sem vara í um 35 ár (svonefnd AMO sveifla), og hefur veiði hnignað á hlýskeiðunum en aukist á kaldskeiðum. Núverandi hlýskeið hófst 1996 og hefur lundaveiði á landsvísu dregist saman um 90% 1995-2018, en samdrátturinn 1995-2007 nemur 73 prósentustigum, þ.e. áður en dregið var úr sókn. Líklegt er að lækkuð viðkoma á landsvísu skýri að mestu þennan samdrátt í veiðum, sem aftur endurspeglar neikvæð áhrif hitabreytinga og hugsanlega fleiri umhverfisþátta á aðalfæðutegundir lunda hérlendis, sandsíli og loðnu.

Iceland Can Be Considered Volcanologist “Heaven”
Iceland can be considered volcanologist “heaven” 1) Sub-aerial continuation of the Mid-Atlantic Ridge 2) Intersection of a mantle plume with a spreading ocean ridge 3) Volcanism associated with tectonic rifting 4) Sub-glacial volcanism 5) Tertiary flood (plateau) basalts 6) Bi-modal volcanism 7) Submarine volcanism 8) 18 historically active volcanoes 9) Eruptions roughly every 5 years 1. The North Atlantic opened about 54 Ma separating Greenland from Europe. 2. Spreading was initially along the now extinct Agir ridge (AER). 3. The Icelandic plume was under Greenland at that time. 4.

The Surtsey 1963 eruption plume, characteristics and tephra dispersal Einar Sindri Ólafsson (1), Magnus T Guðmundsson (2), and Esther R. Guðmundsdóttir (3) (1) Institute of Earth Sciences, University of Iceland, Reykjavik, Iceland ([email protected]), (2) Institute of Earth Sciences, University of Iceland, Reykjavik, Iceland ([email protected]), (3) Institute of Earth Sciences, University of Iceland, Reykjavik, Iceland ([email protected]) Surtsey is a basaltic island in the south-western end of Vestmannaeyjar archipelago off the south coast of Iceland and is a part of the Vestmannaeyjar volcanic system. It is built from the ocean floor at about 130 m depth in a series of eruptions during 1963-1967, one of the longest eruption in Iceland in historical times. The eruptions can be split into four phases. The first phase of the eruptions was explosive and phreatomagmatic in character. The aim of this study is to put constraints on the mass of tephra transported with the plume. This is done in two ways: (1) Study soil profiles on Heimaey and on the mainland to look for tephra deposits from Surtsey as well as note contemporary descriptions of tephra fallout; and (2) by compiling existing contemporary records of plume height and use plume height – mass transport systematics to estimate the transport. Finally, we compare the outcomes of (1) and (2). Eruption started on 14 November 1963. It was explosive and fed an eruption plume rising typically to 5-9 km in November and December 1963. -
Phoca Vitulina) in Icelandic Waters
Monitoring trends in the abundance of harbour seals (Phoca vitulina) in Icelandic waters Erlingur Hauksson Fornistekkur 14, IS-109 Reykjavik, Iceland ABSTRACT Harbours seal ( Phoca vitulina) numbers along the coast of Iceland were monitored by aerial survey in the period 1980-2006. Trends in the abundance of the harbour seal population on the whole coast and in coastal regions of Iceland waters were estimated using ANCOVA on the sur - vey counts, corrected for the influence of several covariates. Harbour seals were found in every coastal area, but were most abundant in Faxaflói, Breiðafjörður and on the northwest coast in the beginning of this study. Harbour seal numbers declined significantly at a rate of res t = -0.04 (SE 0.005) y r-1 during this period. Decline was highest in Faxaflói and at the south coast ( ≅7%), while the east coast experienced a significant but lesser ( ≅1%) decline. Other coastal areas did not show significant trends. The northwest coast was the richest harbour seal area in Iceland in 2006. In Icelandic waters seals are commercially harvested, and unreported but probably high numbers of harbour seals are killed intentionally by shooting and accidentally in fishing gear each year. These factors likely contributed to the overall observed decline in seal numbers. Hauksson, E. 2010. Monitoring trends in the abundance of harbour seals ( Phoca vitulina ) in Icelandic waters.

Our project contributes to the ongoing work on improving Hekla’s monitoring and early warning systems. In 2012 we began monitoring gas release at Hekla. The dataset comprises semi-permanent near-real time measurements with a MultiGAS system, quantification of diffuse gas flux, and direct samples analysed for composition and isotopes (d13C, dD and d18O). In addition, we used reaction path modelling to derive information on the origin and reaction pathways of the gas emissions. 13 Hekla’s quiescent gas composition was CO2-dominated (0.8 mol fraction) and the d C signature was consistent with pub- lished values for Icelandic magmas. The gas is poor in H2O and S compared to hydrothermal manifestations and syn-eruptive emissions from other active volcanic systems in Iceland. -
The Eruption on Heimaey, Vestmannaeyjar, Iceland
Man Against Volcano: The Eruption on Heimaey, Vestmannaeyjar, Iceland This booklet was originally published in 1976 under the title "Man Against Volcano: The Eruption on Heimaey, Vestmann Islands, Iceland." The revised second edition was published in 1983. This PDF file is a recreation of the 1983 booklet. Cover photograph: View looking southeast along streets covered by tephra (volcanic ash) in Vestmannaeyjar: Eldfell volcano (in background) is erupting and fountaining lava. View of Heimaey before the eruption: Town of Vestmannaeyjar with Helgafell in the right back- ground (photo courtesy of Sólarfilma). Man Against Volcano: The Eruption on Heimaey, Vestmannaeyjar, Iceland by Richard S. Williams, Jr., and James G. Moore Preface The U.S. Geological Survey carries out scientific studies in the geological, hydrological, and cartographic sciences generally within the 50 States and its territories or trusteeships, but also in cooperation with scientific organizations in many foreign countries for the investigation of unusual earth sciences phenome- na throughout the world. In 1983, the U.S. Geological Survey had 57 active sci- entific exchange agreements with 24 foreign countries, and 47 scientific exchange agreements were pending with 30 foreign countries. The following material discusses the impact of the 1973 volcanic eruption of Eldfell on the fishing port of Vestmannaeyjar on the island of Heimaey, Vestmannaeyjar, Iceland. Before the eruption was over, approximately one-third of the town of Vestmannaeyjar had been obliterated, but, more importantly, the potential damage probably was reduced by the spraying of seawater onto the advancing lava flows, causing them to be slowed, stopped, or diverted from the undamaged portion of the town. -
The Best of Iceland
04_178416-ch01.qxp 5/29/08 8:59 AM Page 1 1 The Best of Iceland On each trip to Iceland, we are always struck by how often other travelers are—or intend to be—repeat visitors. Many come year after year, never exhausting Iceland’s endless variations of magnificent scenery and adventure. Returning travelers immedi- ately recognize the crisp, invigorating polar air, and what W. H. Auden called “the most magical light of anywhere on earth.” Iceland’s astonishing beauty often has an austere, primitive, or surreal cast that arouses reverence, wonderment, mystery, and awe. Lasting impressions could include a lone tuft of wildflowers amid a bleak desert moonscape or a fantastical promenade of icebergs calved into a lake from a magisterial glacier. The Icelandic people—freedom-loving, egalitarian, self-reliant, and worldly—are equally exceptional. They established a parliamentary democracy over a millennium ago, and today write, publish, purchase, and read more books per capita than any peo- ple on earth. Reykjavík, their capital, has become one of the world’s most fashionable urban hot spots. In November 2007, the U.N. named Iceland the world’s best coun- try to live in, based on life expectancy, education levels, medical care, income, and other criteria. 1 The Best Natural Wonders • Glymur: Iceland’s tallest waterfall is • Blue Lagoon: The central activity nimble and graceful: Streamlets at this spa—Iceland’s top tourist descend like ribbons of a maypole attraction—is bathing in a shallow, into a fathomless canyon mantled in opaque, blue-green lagoon amid a bird nests and lush mosses.
