title: Data and Code for: The Inverse Product Differentiation Logit Model

description: We introduce the inverse product differentiation logit (IPDL) model, a micro-founded inverse market share model for differentiated products that captures market segmentation according to one or more characteristics. The IPDL model generalizes the nested logit model to allow richer substitution patterns, including complementarity in demand, and can be estimated by linear instrumental variables regression with market-level data. Furthermore, we provide Monte Carlo experiments comparing the IPDL model to the workhorse empirical models of the literature. Lastly, we demonstrate the empirical performance of the IPDL model using a well-known dataset on the ready-to-eat cereals market.

title: Palynological dataset at ODP Site 882 (North Pacific) during the Plio-Pleistocene

description: This data set presents the palynological row data performed on sediment samples from the ODP Hole 882A (50°21.79'N, 167°35.99'E, 3244 m) drilled on the Detroit Seamount in the northern part of the Hawaiian-Emperor Seamount Chain in the North Pacific Ocean during the Plio-Pleistocene. A total of 44 samples were analyzed for their palynological contents using a transmitted light microscope at 250× to 1000× magniﬁcation. The palynomorphs analyzed included dinocysts, acritarchs, pollen grains, spores and other palynofacies. In the study sequence, the assemblages are characterized by 33 dinocyst species, 2 acritarch taxa, 8 pollen morphotypes. Row counts are shown (number of identified specimens), as well as labels, depth (in mcd) and estimated age (Ma) of the studied samples.

title: Marine palynomorph abundance estimates of sediment core CRP-2A (Fig. 2)

description: A diverse assemblage of marine palynomorphs was recovered from the Oligocene - Miocene section of CRP-2/2A. Most of the assemblage is composed of previously unrecognised species. Three distinct groups of marine palynomorph were recognised: (1) prasinophytes, mainly Cymatiosphaera, (2) acritarchs, mainly Leiosphaeridia and Sigmopollis although Leiofusa is an important component of the bottom half of the hole, and (3) dinoflagellate cysts. About 27 species of in situ dinoflagellate cysts were recorded, of which seven apparently undescribed species of Lejeunecysta form a prominent component. Reworked specimens of several species of the Paleogene Transantarctic Flora occur in CRP-2/2A sediments. Several abundance peaks of reworked taxa from the Transantarctic Flora are recorded. Three marine palynomorph zones were recognised (MP3, MP2, MP1), considered to be early Oligocene, late Oligocene, and late Oligocene/early Miocene in age respectively. Samples from the Quaternary and Pliocene part of CRP-2/2A were also examined. These proved either barren or yielded very sparse low diversity floras.

title: Multibeam bathymetry raw 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 raw and unprocessed bathymetric and backscatter data is stored in Kongsberg format (*.all), each containing up to 30 min of data. The therein included 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 but can be extracted from the *.all files.

title: Stratigraphic distribution of marine palynomorph species recorded for the Miocene of ODP Hole 105-645E (Table 1)

description: A total of 145 samples were analyzed for palynology, and all were found to be productive. Residues are dominated by pollen, terrestrial spores, and land plant tissues. Marine palynomorphs occur in all samples, which allowed us to recognize five Miocene dinocyst assemblage zones. Dinocyst assemblages indicate cool-water conditions and suggest a neritic rather than fully oceanic environment, with not only North Atlantic and Norwegian Sea affinities, but also containing both notable protoperidiniacean and possible endemic elements. Dinocyst assemblages indicate an early Miocene age for the bottom of Hole 645E and an age no younger than early late Miocene (Sample 105-645E-24R, CC) near the top of the interval studied. These age assignments provide an estimated initiation of ice rafting in Baffin Bay at between 7.4 and 9.5 Ma. Increased terrigenous influx and apparent disappearance of certain dinocyst taxa occur in the middle to late Miocene and may be related to oceanographic changes or climatic deterioration. Spores and pollen indicate a climate that varied within a temperate regime during the early and middle to early late Miocene, followed by climatic deterioration.Four new dinocyst species are described: Batiacasphaera gemmata, Impletosphaeridium prolatum, Operculodinium vacuolatum, and Selenopemphix brevispinosa. The acritarch genus Cyclopsiella Drugg and Loeblich is emended, and two new combinations have been created: Cyclopsiella granosa (Matsuoka) and Cyclopsiella? laevigata (Chateauneuf). Cyclopsiella granosa (Matsuoka) n. comb. is considered a subjective junior synonym of Cyclopsiella granulata He and Li. Ascostomocystis granulatus Chateauneuf has been provisionally allocated to Cyclopsiella and renamed Cyclopsiella? chateauneufii. Two new acritarch species are described: Cyclopsiella spiculosa and Cymatiosphaera! baffinensis.

title: (Table T1) Kerogen and organic constituents in ODP Hole 183-1138A, Kerguelen Plateau

description: Mid-Cretaceous sediments recovered during Ocean Drilling Program Leg 183 (Cores 183-1138A-69R to 73R) on the central Kerguelen Plateau have been analyzed palynologically and paleobotanically to determine the age of the strata and to reconstruct vegetational development and paleoecology. The lower strata (Cores 183-1138A-71R to 73R), a dark, organic-rich silty claystone with many wood fragments and fern remains (sedimentary Unit VI), certainly of terrestrial origin, directly overlies the volcanic basement, which is dated as latest Albian (~95 to 103 Ma) to earliest Cenomanian. The age of the terrestrial strata can be determined by sporomorphs as late Albian to earliest Cenomanian as well. This shows that parts of the central Kerguelen Plateau must have been subaerial at least until the late Albian and were covered with a diverse high-latitude flora, probably dense conifer forest with various fern taxa in the undergrowth. Early angiosperms are also present. The vegetational character represented in Unit VI did not change significantly through time. However, varying percentages of several sporomorph groups seem to show recurring abundance variations, which might possibly be cyclic, caused by Milankovitch-type cyclic events. Cores 183-1138A-67R through 69R, of open marine origin, contain medium- to high-diversity dinocyst assemblages. Based on previous stratigraphic zonation schemes, the ages of these strata range within the Heterosphaeridium Superzone, from the Palaeohystrichophora infusorioides Zone to the Conosphaeridium striatoconus Zone, which correlates to the latest Cenomanian to Coniacian.

title: Dinoflagellate cysts counts of sediment core MD95-2042

description: Dinoflagellate cysts were analysed from IMAGES core MD952042 (37°48?N; 10°01?W) retrieved from the Tagus Abyssal Plain. Previous results of stable isotope and magnetic susceptibility measurements as well as of planktonic foraminiferal temperature reconstruction from this core, suggest the occurrence of “Heinrich-like events” (i.e. large ice-sheet decay) during Marine Isotopic Stage 5 (MIS 5). Dinoflagellate assemblages of this time period have revealed six dinocyst events that are characterised by peaks in Bitectatodinium tepikiense percentages. These events occur synchronously with “Heinrich-like events” previously identified. They are coeval with major retreats of the forest on land, indicating, therefore, drastic changes in the regional climate. However, results from the Ice-Rafted Detritus (IRD) analysis of the &gt;150 ?m lithic fraction shows that MIS 5 of MD952042 has only recorded one significant input of iceberg discharge, located at the MIS 6/MIS 5 transition. It seems therefore that it is the only event that could be called a “true Heinrich event”.

title: Multibeam bathymetry processed data (Kongsberg EM 122 transit dataset, Generic sensor format) 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).
