  • Distribution of Marine Palynomorphs in Surface Sediments, Prydz Bay, Antarctica
    DISTRIBUTION OF MARINE PALYNOMORPHS IN SURFACE SEDIMENTS, PRYDZ BAY, ANTARCTICA Claire Andrea Storkey A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree Masters of Science in geology School of Earth Sciences Victoria University of Wellington April 2006 ABSTRACT Prydz Bay Antarctica is an embayment situated at the ocean-ward end of the Lambert Glacier/Amery Ice Shelf complex East Antarctica. This study aims to document the palynological assemblages of 58 surface sediment samples from Prydz Bay, and to compare these assemblages with ancient palynomorph assemblages recovered from strata sampled by drilling projects in and around the bay. Since the early Oligocene, terrestrial and marine sediments from the Lambert Graben and the inner shelf areas in Prydz Bay have been the target of significant glacial erosion. Repeated ice shelf advances towards the edge of the continental shelf redistributed these sediments, reworking them into the outer shelf and Prydz Channel Fan. These areas consist mostly of reworked sediments, and grain size analysis shows that finer sediments are found in the deeper parts of the inner shelf and the deepest areas on the Prydz Channel Fan. Circulation within Prydz Bay is dominated by a clockwise rotating gyre which, together with coastal currents and ice berg ploughing modifies the sediments of the bay, resulting in the winnowing out of the finer component of the sediment. Glacial erosion and reworking of sediments has created four differing environments (Prydz Channel Fan, North Shelf, Mid Shelf and Coastal areas) in Prydz Bay which is reflected in the palynomorph distribution. Assemblages consist of Holocene palynomorphs recovered mostly from the Mid Shelf and Coastal areas and reworked palynomorphs recovered mostly from the North Shelf and Prydz Channel Fan.

Thanks to the small size of the watersheds and the close proximity of the depositional environment to the mainland, the Bay of Brest represents an ideal case study for palynological investigations.

PALYNOLOGY AND DINOCYST BIOSTRATIGRAPHY OF THE LATE MIOCENE TO PLEISTOCENE, NORWEGIAN SEA: ODP LEG 104, SITES 642 TO 6441,2 Peta J. Mudie3 ABSTRACT Cores from ODP Leg 104 Holes 642A, 642B, 642C, 644A, and 644B were sampled at intervals of 40 cm to 100 cm for a detailed study of palynomorphs and palynodebris types in upper Cenozoic sediments of the Vetoing Plateau. Core- catcher samples were also studied from Hole 643A on the seaward flank of the plateau. Most of the 600 samples studied contained dinoflagellate cysts, pollen, spores, and various types of palynodebris. Total numbers of indigenous dino- cysts, and pollen-spore concentrations show cyclical variations which appear to correspond to climate fluctuations in Pliocene and younger sediments, and to either climatic changes or phytoplankton productivity cycles in the older sedi­ ments. Stratigraphic ranges for 68 cyst morphotypes were used to erect a provisional dinocyst zonation that can be cor­ related with other Northern Hemisphere high-latitude zonations. Four dinocyst zones are defined, with boundaries cor­ responding to biochronological or magnetostratigraphic ages of ca. 15 Ma, 9 Ma, 4.2 Ma, and 1.4 Ma. Environmental changes are interpreted in terms of (a) a progressive decline in species diversity due to the disappearance of subtropical species; (b) appearance of subarctic North Pacific taxa, presumably from the Arctic Ocean; and (c) an increase in heterotrophic protoperidinioid cyst species during the Pleistocene.

  • From Greenhouse to Icehouse; Organic-Walled Dinoflagellate Cysts As Paleoenvironmental Indicators in the Paleogene
    Earth-Science Reviews 68 (2005) 281–315 www.elsevier.com/locate/earscirev From greenhouse to icehouse; organic-walled dinoflagellate cysts as paleoenvironmental indicators in the Paleogene Appy Sluijsa,*,Jo¨rg Prossa,b,c, Henk Brinkhuisa a Laboratory of Palaeobotany and Palynology, Utrecht University, Budapestlaan 4, NL-3584 CD Utrecht, The Netherlands b Institute of Geosciences, Tu¨bingen University, Sigwartstraße 10, D-72076 Tu¨bingen, Germany c Institute of Geology and Paleontology, Frankfurt University, Senckenberganlage 32-34, D-60054 Frankfurt, Germany Received 27 May 2004 Abstract Dinoflagellates are an important component of the extant eukaryotic plankton. Their organic-walled, hypnozygotic cysts (dinocysts) provide a rich, albeit incomplete, history of the group in ancient sediments. Building on pioneering studies of the late 1970s and 1980s, recent drilling in the Southern Ocean has provided a wealth of new dinocyst data spanning the entire Paleogene. Such multidisciplinary studies have been instrumental in refining existing and furnishing new concepts of Paleogene paleoenvironmental and paleoclimatic reconstructions by means of dinocysts. Because dinocysts notably exhibit high abundances in neritic settings, dinocyst-based environmental and paleoclimatic information is important and complementary to the data derived from typically more offshore groups as planktonic foraminifera, coccolithophorids, diatoms and radiolaria. By presenting case-studies from around the globe, this contribution provides a concise review of our present understanding of the paleoenvironmental significance of dinocysts in the Paleogene (65–25 Ma). Representing Earth’s greenhouse–icehouse transition, this episode holds the key to the understanding of extreme transient climatic change. We discuss the potential of dinocysts for the reconstruction of Paleogene sea-surface productivity, temperature, salinity, stratification and paleo-oxygenation along with their application in sequence stratigraphy, oceanic circulation and general watermass reconstructions.

  • Eutrophication Driven by Aquaculture Fish Farms Controls Phytoplankton and Dinoflagellate Cyst Abundance in the Southern Coastal Waters of Korea

Water temperature showed seasonality, whereas salinity and pH remained relatively consistent. Dissolved inorganic nutrient levels were higher in September and at the inner stations, where aquaculture fish farms are located than those in May and at the outer stations. Canonical correspondence analysis and artificial neural network analysis revealed multiple environmental factors that affect the distribution of phytoplankton and dinoflagellate cysts. Diatoms dominated in the phytoplankton assemblages, while the protoperidinioid group dominated in the dinoflagellate cyst assemblages. Cyst abundance was higher at the outer stations than at the inner stations due to transport by fast currents, and phytoplankton abundance was positively correlated with cyst abundance. An increase in diatom abundance led to an increase in heterotrophic/mixotrophic cyst abundance, indicating that excessive Citation: Kang, Y.; Kim, H.-J.; Moon, uneaten food and urinary waste from the fish farms caused eutrophication in the study region and fast C.-H.

A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age. Read More Answers. Question # 2 What is monograph? Answer:- A monograph is a specialist work of writing (in contrast to reference works) on a single subject or an aspect of a subject, usually by a single author. Read More Answers. Question # 3 What is spore? Answer:- In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoebulae into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. Read More Answers. Question # 4 What is chitinozoan? Answer:- Chitinozoa are a taxon of flask-shaped, organic walled marine microfossils produced by an as yet unknown animal. Common from the Ordovician to Devonian periods, the millimetre-scale organisms are abundant in almost all types of marine sediment across the globe. This wide distribution, and their rapid pace of evolution, makes them valuable biostratigraphic markers.
