title: Multibeam bathymetry processed data (Kongsberg EM 122 transit dataset) of RV SONNE during cruise SO292/2, North Pacific Ocean

description: The multibeam echo sounder (MBES) data was collected from the 10.07.2022 (09:24 UTC) when leaving the Northern Mariana EEZ to the 18.07.2022 (00:24 UTC) before entering the EEZ close to the Aleutian Islands, Alaska with the Kongsberg EM122 on RV SONNE in the North Pacific Ocean (SO292/2). The deep-water MBES EM122 operates with an acoustic frequency of 12 kHz and a beam opening angle of 0.5° x 1°. The time, motion and position data (WGS84, geographic) was measured by the Kongsberg Seapath system on board. During the acquisition the echo sounder was monitored as well as settings and filter adjusted according to the environment. The transit speed was up to 13 knots. The swath opening angle was set between 60° and 65° resulting in a swath width of about 22 km in 5,000 m water depth. The Ping Mode was set to Auto, which enabled the system to use continuous wave pulses in shallow modes and frequency modulated pulses in deep modes. Further, high density and dual swath mode were continuously applied. As the data was collected during transit, no specific surveys were performed. When sound velocity related artefacts were noticed in the MBES data, the sound velocity profile in the MBES acquisition software SIS was updated. Profiles were measured using XSVs (Expendable Sound Velocity) up to a depth of 2,000 m on the 11.07.2022, 13.07.2022 and 16.07.2022. Additionally, synthetic SVPs extracted form the World Ocean Altlas 2009 from NOAA (Levitus, 2013) using the software "Sound Speed Manager" (developed by the UNH Center for Coastal and Ocean Mapping and NOAA Coast Survey Development Laboratory (CSDL)) were applied. The SVP data is not part of this submission.The data was post-processed using the software QPS Qimera v.2.4.9. No further SVP re-computation, navigation correction or tide correction was applied. Erroneous depth measurements were deleted manually by using the swath and slice editor. The vertical datum is mean sea level (MSL). The cleaned data was exported in gsf format as well as bathymetric grids in a resolution of 100 m (geotiff format, projected coordinates WGS84/UTM zone 55N (EPSG: 32655).

title: Multibeam bathymetry processed data (Kongsberg EM 122 working area dataset, Generic sensor format) of RV MARIA S. MERIAN during cruise MSM112/2, Atlantic Ocean

description: The multibeam echo sounder (MBES) data was collected from the 24.11.2022 (02:52 UTC) to the 03.12.2022 (22:52 UTC) with the Kongsberg EM122 on RV Maria S. Merian during the transit from Cartagena (Colombia) to Las Palmas (Canary Islands, Spain) in the Atlantic Ocean. The deep-water MBES EM122 operates with an acoustic frequency of 12 kHz and a beam opening angle of 2° x 2°. The system was used in the dual-swath mode with up to 864 beams per ping. During the acquisition the echo sounder was monitored as well as settings and filter adjusted according to the environment. The swath opening angle was set between 65° and 70°. As the data was collected during transit, no specific survey was performed.Sound velocity profiles (SVP) were measured on the 23.11., 25.11., 29.11., and 30.11.22 with a CTD and applied in the MBES acquisition software SIS to ensure high quality measurement. The SVP data is not part of this submission but can be extracted from the *.all files. The data was post-processed using the software QPS Qimera. No further navigation or tide correction was applied. The SVP profiles were re-applied to the data by using the nearest in time. Erroneous depth measurements were deleted manually by using the swath and slice editor. The vertical datum is mean sea level (MSL). The cleaned data was exported in gsf format.

title: Multi-proxy analysis of sediment cores from Lake Caldeirão (Azores archipelago, Portugal)

description: The Azores archipelago is a group of nine oceanic volcanic islands located in the mid-North Atlantic, roughly 1500 km from Europe and 1900 km from America. Lake Caldeirão is situated in the central caldeira of Corvo Island at 399 m altitude. A coring campaign was conducted in June 2017 using a 60mm diameter UWITEC gravity corer from UWITEC floating platform retrieving a core (4.60 m long) located in the deepest part of the lake. The core was dated using ¹⁴C and produced a multi-proxy dataset of geochemical and biological analyses that we used to uncover paleoenvironmental changes on Lake Caldeirão in the last 1500 years

title: Record of dinocyst assemblage compositions from sediment core GeoB19927-3 during the Holocene

description: The dataset contains abundances of dinoflagellate cysts (dinocysts) from sediment samples from sediment core GeoB19927-3 (73°35,26' N, 58°05,66' W) located in Southern Melville Bay (Baffin Bay). The dataset covers the depth interval between 760-0 cm top depths, corresponding to 7.7 kyrs BP – present. The core was taken at 932 meters of water depth by gravity coring during cruise MSM44 in 2015 (Dorschel et al., 2016). The core consists of 1147 cm of sediment. For dinocyst analysis, it was sub-sampled every centimetre within the top 25 cm, every 5 cm within the 25 cm to 280 cm interval and every 10 cm within the 280 cm to 760 cm interval, including 124 samples. Sample processing followed the procedure for palynological preparation described in Vernal et al. (2010). The taxonomy of dinocysts used here was based on Rochon et al. (1999) and de Vernal et al. (2020). At least 300 dinocyst specimens were counted per sample when possible. For samples with low dinocyst abundance as many specimens as possible were enumerated. In the sample with lowest dinocyst abundance, 89 specimens were counted. The chronology has been provided by Saini et al. (2020).

title: Occurence of marine palynomorphs of sediment core CRP-1 (Table 1)

description: The first core of the Cape Roberts Project, CRP-1, penetrated a Quaternary and lower Miocene section rather than the anticipated Palaeogene sediments. Initial palynologic study was conducted at the Crary Science and Engineering Laboratory, McMurdo Station, concurrent with drilling. Rapid and environmentally safe sample processing was made possible by the use of a focused microwave digestion unit that scrubbed acid fumes. In situ and/or reworked dinocysts (dinoflagellate cysts), acritarchs (leiospheres and acanthomorphs), and prasinophyte phycomata are present in the 35 samples studied. Overall, the CRP-1 assemblages are similar to Arctic marine palynomorph assemblages that are used there as ice margin indicators. Some of the acanthomorph acritarchs recovered from the CRP-1 core closely resemble cysts of extant Antarctic autotrophic sea-ice dinoflagellates. It is possible that some of these acanthomorphs are actually dinocysts, and could be used as indicators of sea-ice conditions similar to today.Most of the in situ marine palynomorphs are undescribed taxa and thus are presently of little biostratigraphic value. Dating of the core was based on diatom, palaeomagnetic and strontium isotope studies. The upper 43.55 mbsf of the core are Quaternary in age and the rest of the core, down to the bottom at 147.69 mbsf, is of early Miocene age. Although not biostratigraphically significant, the dinocysts are the first in situ Quaternary and Miocene dinocysts reported from East Antarctica, and constitute the most diverse assemblage recovered from any firmly dated Neogene section from Antarctica. In addition, they confirm that cyst-producing dinoflagellates were present in Antarctic waters during the Neogene and Quaternary.The core can be divided into three intervals based on their palynomorph assemblages (Quaternary, 0-43.55 mbsf; lower Miocene, 43.55-99.10 mbsf; and lower Miocene, 99.10- 147.69 mbsf). The distinctive palynomorph assemblages are interpreted to reflect changing climatic conditions that prevailed at the time of deposition. Overall, conditions appear to have deteriorated up-section.

title: Dinoflagellate cysts in the Oligocene to Miocene sediments of IODP Site 318-U1356A

description: There is growing interest in the scientific community in reconstructing the paleoceanography of the Southern Ocean during the Oligocene-Miocene because these time intervals experienced atmospheric CO2 concentrations with relevance to our future. However, it has remained notoriously difficult to put the sedimentary archives used in these efforts into a temporal framework. This is at least partially due to the fact that the bio-events recorded in organic-walled dinoflagellate cysts (dinocysts), which often represent the only microfossil group preserved, have not yet been calibrated to the international time scale. We here present dinocyst ranges from Oligocene-Miocene sediments drilled offshore the Wilkes Land continental margin, East Antarctica (Integrated Ocean Drilling Program (IODP) Hole U1356A). In addition, we apply statistical means to test a priori assumptions about whether the recorded taxa were deposited in situ or were reworked from older strata. Moreover, we describe two new dinocyst species, Selenopemphix brinkhuisii sp. nov. and Lejeunecysta adeliensis sp. nov., which are identified as important markers for regional stratigraphic analysis. Finally, we calibrate all identified dinocyst events to the international time scale using independent age control from calcareous nannoplankton and magnetostratigraphy from IODP Hole U1356A, and propose a provisional dinoflagellate cyst zonation scheme for the Oligocene-Miocene of the Southern Ocean.

title: Regression of Globorotalia scitula of sediment core M51/3_567_SL104

description: The table provides parameters (dip, intercept, and adjusted R2) of a linear regression of the coordinates of suture points in shells of G. scitula in relation to the shell centre of spiralization. For this, the xy-coordinates were transformed into polar coordinates with the parameters theta (angle between suture point and spiralization centre) and t (distance between suture point and spiralization centre), normalized for a unity maximum diameter of t=1 per specimen. This coordinate notation allowed to describe a spiral (i.e. periodic function) more efficiently. The coordinates could then be logarithmically plotted as theta over t, and subjected to a linear regression to determine the dip (theta/t) and intercept (theta) as well as the adjusted R2 of the resulting line of regression.

title: Palynological analyses of the sediments around the Miocene/Pliocene boundary in ODP Hole 151-911A

description: The late Neogene evolution of the Arctic to Subarctic region is poorly understood due to few available records and poor age control. At the margin of the Arctic Ocean, Yermak Plateau Ocean Drilling Program (ODP) Hole 911A is strategically located for establishing a stratigraphic framework for the Arctic. Here we present dinoflagellate cyst and acritarch data from 24 stratigraphic levels in the lower part (474.26-505.64 metres below the seafloor (mbsf)) of ODP Hole 911A. The marine palynomorphs indicate a latest Miocene to earliest Pliocene age (between 5.8 and 5.0 Ma) for the base of the hole based on the co-occurrence of the dinoflagellate cyst Barssidinium evangelineae and acritarch Lavradosphaera crista. Our age estimate for the sediments can possibly be further refined to 5.0-5.33 Ma based on the presence of Achomosphaera andalousiensis suttonensis, which apparently has a range restricted to the Pliocene. An age close to the Miocene/Pliocene boundary agrees with the planktonic foraminifer data. Together with recently available magnetostratigraphic data, the base of the hole is likely to be placed at ~5.2 Ma. This new chronostratigraphy is a first step towards a better understanding of the late Neogene palaeoenvironment for the Yermak Plateau and also for the wider Arctic to Subarctic region.The terrestrial and fresh water palynomorphs were most likely redistributed and/or displaced from the shelf towards deeper parts of the basin during contourite deposition under the influence of the West Spitsbergen Current. The in situ marine dinoflagellate cyst assemblage contains a mixture of cool water and thermophilic taxa, indicating sea-ice free, cool-temperate, warmer than present conditions at the Yermak Plateau. Rivers were likely the source for the freshwater influence.

title: Dinoflagellate cyst counts of sediment core GIK23071-3

description: Marine sediments from the Vøring Plateau (Norwegian Sea) have been studied for their dinoflagellate cyst (dinocyst) and foraminiferal content in order to reconstruct sea-surface conditions in the eastern Norwegian Sea during Marine Isotope Stage (MIS) 5e. In combination with stable oxygen isotope and ice rafted detritus (IRD) data, the variations in foraminiferal and dinocyst assemblage composition reflect a stepwise transition from the final phase of deglaciation (Termination II) into typical interglacial conditions. This stepwise change is repeated subsequently during the cooling conditions of glacial inception towards MIS 5d. The interval studied is characterized by relatively high abundances of Bitectatodinium tepikiense, in comparison to present-day values in the area, indicating a larger seasonal temperature amplitude with enhanced surface water stratification during MIS 5e. The important occurrence of the warm-temperate dinocyst Spiniferites mirabilis s.l. concurrent with subpolar foraminifers Turborotalita quinqueloba, Globigerina bulloides, and Globigerinita glutinata reveals that most pronounced interglacial marine conditions prevailed in the area just prior to the transition towards MIS 5d. The late stratigraphic position of this phase in the interglacial is verified by comparison with dinocyst data from south of Iceland, manifesting its over-regional implication. Besides the good agreement in dinocyst and foraminiferal assemblage changes, the variations in and between both fossil assemblages also point to the existence of some significant surface water variability in the eastern Norwegian Sea during MIS 5e.
