    Description / Table of Contents: Fjords are glacially over-deepened, semi-enclosed marine basins, but are often neglected as a sedimentary realm. They represent the transition from the terrestrial to the marine environment and as such have the potential to preserve evidence of environmental change. Typically most fjords have been glaciated a number of times and some high-latitude fjords still possess a resident glacier. The stratigraphic record in fjords largely preserves a glacial deglacial cycle of deposition. Sheltered water and high sedimentation rates potentially make fjords ideal depositional environments for preserving continuous records of climate and environmental change with high temporal resolution. Fjords are also referred to as miniature oceans providing the unique opportunity to study marine processes in great detail. With predictions of warming climates, changing ocean circulation and rising sea levels, this volume is a timely look at these environmentally sensitive coastlines.

    Multibeam bathymetry and the depositional environments of Kongsfjorden and Krossfjorden, western Spitsbergen, Svalbard (2003)

    Notes: Kongsfjorden and Krossfjorden are two ice-proximal fjords on the western coast of Spitsbergen which have been surveyed using multibeam bathymetry, sub-bottom profiling and gravity coring. Central and outer Kongsfjorden is dominated by a 30 km2 outcrop of bedrock, with a thin (〈10m) sediment cover. The bedrock displays a relict sub-glacial, ice-scoured topography produced during the glacial re-advances of the Weichselian (20 Ky BP) and again during the last major Holocene re-advance of the Little Ice Age (550-200 yrs BP). Drumlins and glacial flutes are common across the floor of Kongsfjorden, with lengths of 1.5-2.5 km and widths of 〈100 m, rising up to 10 m in water depths of 〈100 m. This topography is smoothed by bottom currents from the wind-driven forcing of surface waters. The flow is counter-clockwise, matching boundary layer movement under the influence of Coriolis force. Both fjords are characterized by a variable acoustic character, based on sub-bottom profile data. The deepest basins are dominated by parallel, well-laminated reflectors and an irregular-transparent acoustic character indicating the presence of Holocene-age fine-grained sediments up to 30 m thick. A parallel, irregular-transparent acoustic character with waveform morphology in inner Kongsfjorden is interpreted as moraines, originating from the 1948 and 1869 surges of Kronebreen glacier. Mass-flows are common on the flanks of topographic highs as acoustically chaotic-transparent lensoid and wedge-shaped reflectors. The sediments of outer and central Kongsfjorden are characterized by bioturbated, gas-rich homogeneous muds interpreted as being the result of the settling of fine-grained sediment and particulate suspensions.

    Turbidite and contourite sediment waves in the northern Rockall Trough, North Atlantic Ocean (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 43 (1996), S. 0 
    Details
    ISSN: 1365-3091
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: Two sediment wave fields have been identified in the northern Rockall Trough; one from the north-eastern part of the trough, developed on the flank of an elongate sediment drift, and the other at the distal edge of the Barra Fan. Wavelengths in both areas vary from 1 to 2 km and wave heights from 5 to 20 m. The seismic character of both the wave fields is similar with a lower package of well-layered, medium- to high-intensity reflectors migrating upslope, overlain by a dominantly acoustically transparent unit containing irregular, semicontinuous reflectors. Eight cores have been recovered from the two wave fields, seven from the crest-trough areas of the distal Barra Fan wave field, and a single core from the crest of the sediment-drift waves. Lithologically, the cores show that different processes have been active across the two wave fields. Cores from the Barra Fan field contain thin turbidites with thicker, draped hemipelagites and hemiturbidites, corresponding to the well-layered, reflective seismic units and transparent seismic unit, respectively. These waves have been maintained by turbidity currents, perhaps over older, originally bottom-current-formed waves. The single core from the small sediment-drift wave field recovered hemipelagites and glaciomarine sediments grading upwards into muddy-silty contourite deposits, topped by a sandy contourite. These waves were constructed by contour currents. Dating of cores from these two small wave fields revealed that the sequences of thin turbidite and hemipelagite sediments from the Barra Fan correspond to the Late Glacial-Allerød/Bölling Interstadial with the overlying hemipelagite of Younger Dryas-Holocene age. The contourite deposits from the north-east Rockall Trough wave field have been dated as early Holocene, reflecting increasing bottom-current activity at the changeover from a glacial to an interglacial regime.

    Description: Fjords are glacially over-deepened semi-enclosed marine basins, typically with entrance sills separating their deep waters from the adjacent coastal waters which restrict water circulation and thus oxygen renewal. The location of fjords is principally controlled by the occurrence of ice sheets, either modern or ancestral. Fjords are therefore geomorphological features that represent the transition from the terrestrial to the marine environment and, as such, have the potential to preserve evidence of environmental change. Typically, most fjords have been glaciated a number of times and some high-latitude fjords still possess a resident glacier. In most cases, glacial erosion through successive glacial/interglacial cycles has ensured the removal of sediment sequences within the fjord. Hence the stratigraphic record in fjords largely preserves a glacial-deglacial cycle of deposition over the last 18 ka or so. Sheltered water and high sedimentation rates have the potential to make fjords ideal depositional environments for preserving continuous records of climate and environmental change with high temporal resolution. In addition to acting as high-resolution environmental archives, fjords can also be thought of as mini-ocean sedimentary basin laboratories. Fjords remain an understudied and often neglected sedimentary realm. With predictions of warming climates, changing ocean circulation and rising sea levels, this volume is a timely look at these environmentally sensitive coastlines.

    Dinoflagellate cysts as proxies for palaeoceanographic conditions in Arctic fjords (2010)
    In:  Geological Society Special Publication 344: 61-74.
    Details
    Publication Date: 2010-11-17
    Description: The potential of using dinoflagellate cysts as proxies for palaeoceanographic conditions and as monitors of the dynamic marine environment of climatically sensitive Arctic fjords was investigated with sediment traps. Dinoflagellate cysts were analysed from three separate deployments in two high Arctic fjords in the Svalbard archipelago. Two deployments in Kongsfjorden on the west coast of Svalbard occurred during 2002 and 2006-2007 and a deployment in Rijpfjorden on the NE coast occurred during 2006-2007. The cyst production displayed peaks of abundance in the spring and late summer with distinct differences in cyst occurrence in different fjords and in different years. The recorded and identified cyst species were consistent both with the hydrography of the fjords and with changes in cyst composition that are comparable to the seasonal shifts in water mass characteristics. The presence of the heterotrophic species Protoperidinium conicum in Kongsfjorden during 2002 is of note and may reflect the availability of a particular food source possibly associated with the strong influx of Atlantic Water. Cysts recovered from Kongsfjorden during 2006-2007 were dominated by Islandinium minutum, an indicator of cold, polar to subpolar conditions. The temperature and salinity characteristics of the ambient hydrography in this period indicated less influence by Atlantic Water than in 2002, and the cyst production was consistent with regional cyst distribution patterns. In Rijpfjorden, cyst assemblages were dominated by Pentapharsodinium dalei, consistent with the fjord being dominated by full Arctic conditions during the mooring deployment and the possible occurrence of stratified water with high productivity during the spring phytoplankton bloom.

    Scottish west coast fjords since the last glaciation: a review (2010)
    In:  Geological Society Special Publication 344: 305-329.
    Details
    Publication Date: 2010-11-17
    Description: Evidence from seismic profiles, sidescan and multibeam sonar surveys and sediment cores reveal important information about the depositional history of Scotland's fjords during the last deglacial transition and the subsequent Holocene. Devensian glaciation removed pre-existing sediments both inside and outside the fjord basins, and deposited a diamict over much of the subsequent erosional surface. Glaciomarine sequences deposited during the initial retreat of this ice margin are mainly preserved in the sea area outside the fjords. Younger glaciomarine units present within the fjord basins are often attributed to the later Younger Dryas re-advance (12.8-11.5 ka BP). Younger Dryas ice reworked Devensian sediments, depositing terminal moraines at the mouths of a number of fjords and glaciomarine units within the basins during its retreat. Ice margins oscillated throughout deglaciation, although the latter stages of post-Younger Dryas retreat may have occurred rapidly with topographic pinning an important factor in determining the style of retreat. Holocene records from the fjords are limited, but tentatively support the onshore evidence for a tundra-style landscape in the earliest Holocene, followed by a warming of the climate and, latterly (c. 2000 ka BP), increasing humidity. In the more recent past, human activities such as deforestation, fishing, aquaculture and industry have been recorded in the fjord sediments.
