title: United States earthquake intensity database, 1638-1985

description: The United States Earthquake Intensity Database is a collection of damage and felt reports for over 23,000 U.S. earthquakes from 1638-1985. The majority of intensities are for U.S. cities, but there are also a few earthquakes and intensities for Panama (1925-1975), the Philippines (1926-1937), and Mexico (1887-1981). The data were compiled from various publications, newspaper reports, and special catalogs. The annual serial "United States Earthquakes," is the principal data source and provides 90 percent of the observations. Most records in the file contain the date and time of occurrence and location of the earthquake, magnitude, focal depth, two-digit state code, name and coordinates of observing city or town, the observed intensity at each town, and the distance from city (or locality) to epicenter. The file consists of more than 150,000 earthquake intensity observations. The data file serves as an important information source for the preparation of intensity histories that are useful for environmental and hazard impact statements. NOAA and NCEI make no warranty, expressed or implied, regarding these data, nor does the fact of distribution constitute such a warranty. NOAA and NCEI cannot assume liability for any damages caused by any errors or omissions in these data. If appropriate, NCEI can only certify that the data it distributes are an authentic copy of the records that were accepted for inclusion in the NCEI archives.This dataset has been archived in the framework of the PANGAEA US data rescue initiative 2025.

title: Abundance of mesozooplankton in the Sicily Channel in October 1991. Part 1

description: Mouth diameter of the net was 113 cm, mesh size 200 µm. Samples were immediately fixed with formaldehyde (2-4% final concentration) for specimen identification and counts. Volumes of filtered seawater were estimated by multiplying the area of the net mouth by heights of sampled layers from winch readings. Identification and counts of specimens were performed on aliquots (1/2-1/4) of fixed samples by using a graduate large-bore pipette. Copepods were identified to the species level and separated into females, males and juveniles (copepodites). All other taxa were identified at the species level when possible, or at higher taxonomic levels. Taxonomic identification was done according to the most relevant and updated taxonomic literature.

title: Fecundity (number of offspring) of the calanoid marine copepod Acartia tonsa under combined exposure to hypoxia and marine heatwave events

description: Specimens of the marine calanoid copepod Acartia tonsa were exposed for five days under laboratory conditions to the isolated or combined effects of hypoxia and a marine heatwave event to test for their sex-specific life-history and physiological responses to these stressors. Four treatments were used: Control (C: 18 °C, 100 % O₂ sat.), Hypoxia (H: 18 °C, 35 % O₂ sat.), marine heatwave (MHW: 25 °C, 100 % O₂ sat.) and combined conditions (HMHW: 25 °C, 35 % O₂ sat.). This dataset contains fecundity measurement, represented as the number of offspring (eggs, nauplii and copepodites) spawned by females in each experimental condition following the five-day exposure experiment.
description: The experiment was conducted in the Marine Ecological and Evolutionary Physiology Laboratory (MEEP) at the University of Quebec in Rimouski (UQAR), Rimouski, QC, Canada. Copepods were maintained following the stock culture culturing protocol described in Dam et al. 2021 (https://doi.org/10.1038/s41558-021-01131-5). Namely, approximately 200 copepods were kept in three 5 L aquaria filled with artificial seawater kept at a salinity of 28.4 ± 0.5. The physicochemical parameters of the seawater were the following: temperature of 18 ± 0.4 °C, oxygen saturation of 93.7 ± 6.0 %, pH NBS of 8.20 ± 0.09. The photoperiod was kept at 13h light: 11 h dark. Copepods were fed ad libitum with a mixture of three phytoplankters: Tetraselmis sp., Thalassiosira weissflogii and Rhodomonas salina.----Eggs, offspring and copepodites were retrieved from each aquarium using a 41 µm sieve and placed in a small container. They were then counted one by one under a stereomicroscope (MDF41, Leica) and pipetted in a 500 mL glass beaker.

title: Seawater carbonate chemistry and proton gradients across the coral calcifying cell layer

description: In corals, pH regulation of the extracellular calcifying medium (ECM) by the calcifying cell layer is a crucial step in the calcification process and is potentially important to influencing how corals respond to ocean acidification. Here, we analyzed the growing edge of the reef coral Stylophora pistillata to make the first characterization of the proton gradient across the coral calcifying epithelium. At seawater pH 8 we found that while the calcifying epithelium elevates pH in the ECM on its apical side above that of seawater, pH on its basal side in the mesoglea is markedly lower, highlighting that the calcifying cells are exposed to a microenvironment distinct from the external environment. Coral symbiont photosynthesis elevates pH in the mesoglea, but experimental ocean acidification and decreased seawater inorganic carbon concentration lead to large declines in mesoglea pH relative to the ECM, which is maintained relatively stable. Together, our results indicate that the coral calcifying epithelium is functionally polarized and that environmental variation impacts pHECM regulation through its effects on the basal side of the calcifying cells.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2021) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2022-12-23.The experiments were done in the lab on coral samples that have been held in culture in Monaco for the last 30 years. The data file contains pH data from 3 experiments. In experiment 1corals were kept at seawater pH 8. In experiment 2. Corals were exposed to seawater acidification. In experiment 3 corals were exposed to manipulated DIC concentrations. The data are pH measurements taken from 3 internal compartments of the coral Stylophora pistillata: the mesoglea, the calcifying cells and the ECM.

description: Microscopic charcoal (microcharcoal) was identified in marine sediments of core MD96-2098 located off Namibia and analysed to reconstruct past changes in fire activity of southern Africa (Daniau et al. 2023). Microcharcoal concentrates were obtained after chemical treatment and microcharcoal measured using microscopy. Measurements include microcharcoal concentration (in number of fragments per gram and in µm2 per gram); mean microcharcoal elongation ratio (the lenght to width ratio of particle, and the width to lenght ratio); and percentages of burnt vegetation types. The data covers the past 184,000 years.

title: Blood smear counts of Haemosporidian parasites in Eurasian Jays from Hesse, Germany 2020/21

description: Blood samples of Eurasian Jays Garrulus glandarius (Corvidae, n = 16) were collected by venepuncture in Caldern, Hesse, Central Germany in the years 2020 and 2021 to check for the presence of haemosporidian parasites. We examined Giemsa stained blood smears at × 1000 magnification (light microscope PrimoStar Zeiss, Germany) for at least 10,000 monolayered erythrocytes to calculate infection intensity based on the presence and number of intraerythrocytic gametocytes. The data contains red blood cell counts of blood smears tested positive for haemosporidian parasites (Haemoproteus and Leucocytozoon). All individuals were infected with at least one haemosporidian genus. The most common infection pattern was a mixed infection with Haemoproteus and Leucocytozoon, whereas no Plasmodium infection was detected in any of the samples of the Jays.

title: Reproductive data of Electrona risso, Melamphaes polylepis and Scopelogadus mizolepis from the Eastern Central Atlantic in March and April 2015

description: Knowledge on life history traits of mesopelagic fishes is still sparse. This dataset contains reproductive data of the myctophid Electrona risso (Cocco, 1829) and the melamphaids Melamphaes polylepis Ebeling, 1962 and Scopelogadus mizolepis (Günther, 1878). The specimens were collected in March and April 2015 during cruise 383 of the fishery research vessel "FFS Walther Herwig III" in the Eastern Central Atlantic. A pelagic midwater trawl ("Aalnet", Engel Netze, Bremerhaven Germany) with multiple opening-closing device with three net bags of 20 mm mesh size and 1.8 mm mesh size in the cod-end container was used for catching fish at three depth strata per station between 50 and 700 m depth. Fish was stored in phosphate buffered 4% formalin solution and later on land in laboratories, specimens were measured, weighed, and dissected to examine gonads and oocytes under a stereo microscope. Reproductive phases were assigned based on macroscopic inspection following the standardised terminology for reproductive development in fish by Brown-Peterson et al. (2011, doi:10.1080/19425120.2011.555724). Histological cross sections of selected individuals were used for validation. The Gonadosomatic Index was calculated as GSI = 100 x gonad mass / (total mass – gonad mass). Batch fecundities were determined with the gravimetric method, counting the most advanced eggs in weighed subsamples.
