title: (Table 2) B/Ca, d11B, Mg/Ca and δ¹⁸O record for ODP Hole 130-806B samples

description: We present the first continuous records from 0 to 5 Ma (in 0.333 m.y. integrated time steps) of paired boron/calcium (B/Ca) ratios and boron isotopes (d11B) in the planktonic foraminifera Globogerinoides sacculifer (without sacc) from a site in the western equatorial Pacific Ocean (Ocean Drilling Program Site 806). These measurements, the first made in conjunction with calcification temperature (magnesium/calcium ratios) and average shell mass measurements, indicate that pH is not the sole environmental variable controlling B in planktonic foraminiferal calcite. Our data are consistent with calcification temperature exerting a primary control on B concentration and isotopic composition in planktonic foraminifera. If so, calcification temperature must be taken into account if pH for past oceans and atmospheric pCO2 are to be estimated from B isotope measurements in foraminiferal calcite. Doing so will substantially increase the uncertainty of pH estimates. Although this work was designed as a temporal study, its results define new aspects of calibrating the d11B paleo-pH tracer.

title: Standing belowground plant biomass from the Jena Experiment (Main Experiment, year 2004)

description: This data set contains measurements of standing belowground plant biomass. Data presented here is from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the Main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained in general by bi-annual weeding and mowing. Since 2010, plots were weeded three times per year.In 2004, standing root biomass was sampled in September. Three soil cores with a 4.8 cm diameter per plot were taken to 30 cm depth and pooled plot-wise. The cores were immediately stored cool until further handling. The bulk material of the pooled cores was weighed and cut with scissors to &lt; 1 cm pieces. For root washing, a 50 g subsample was soaked in water and then repeatedly rinsed with tap water over a 0.5 mm sieve. Remaining soil particles were removed by hand. Roots were dried at 60 - 70 °C and weighed subsequently. In 2004, roots were seperated in coarse (diameter &gt; 2 mm) and fine roots after root washing.
description: The Main experiment on the field site of the Jena Experiment comprises a split-plot design in which additional treatments (e.g. no weeding allowing for invasion of other species, or application of fertilizer) have been applied to subplots along the outer margin of the plots (see Treatment description in the section "further details"). While in this dataset only data from the core area (mown and weeding of all none-sown species twice a year, no additional treatments) is reported, all potential treatments are listed as the first parameters in the data file to guarantee compatibility with other datasets that include different treatments. There are two types of missing values contained in the dataset. Empty cells represent missing values that result from the design of the experiment when the respective value does not occur and could thus not be measured. For example, in the columns of species-specific biomass cells are left blank, when the species was not sown into the respective plot. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".This dataset is part of a collection of measurements of belowground plant biomass and morphological root parameters in the Jena Experiment. Similar data from other experiments (e.g. Main Experiment, Dominance Experiment; see details above), other years, or other methods quantifying related data might be available (https://doi.pangaea.de/10.1594/PANGAEA.880330).

title: Morphological root parameters of standing roots from the Jena Experiment (Main Experiment, year 2004)

description: This data set contains measurements of diameter of standing roots. Data presented here is from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below).

The bulk material of the pooled cores was cut with scissors to &lt; 1 cm pieces. A subsample of 50 g was suspended in water and rinsed over a 0.5 mm screen. Roots collected in the screen were transferred into a water-filled clear acrylic tray and scanned. Mean diameter of the roots was determined by using WinRhizo (Regent Instruments, Quebec, Canada).

title: Morphological root parameters of newly formed roots from the Jena Experiment (Main Experiment, year 2003)

description: This data set contains measurements of morphological root parameters, i.e. length and diameter of newly built roots. Data presented here is from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the Main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Since 2010, plots were weeded three times per year.In June 2003, five soil cores with a 4.8 cm diameter per plot were taken to 30 cm depth. The removed soil was replaced by root-free soil from the field site. In September 2003, the initially root-free ingrowth cores were removed and the holes were refilled with root-free soil until the following withdrawal in July 2004. To extract the newly formed roots, each ingrowth core was first weighed and carefully homogenized. A subsample of 50 g of soil was suspended in water and rinsed over a 0.5 mm screen. Roots collected in the screen were transferred into a water-filled clear acrylic tray and scanned. Total root length and mean diameter were determined by using WinRhizo (Regent Instruments, Quebec, Canada). Afterwards, root length density (cm root length per cm3 soil volume) was calculated.

title: Ontogenetic scale cortisol, body condition, and gut content analyses of juvenile milkfish (Chanos chanos) cultured in commercial marine cage systems

description: To quantify chronic stress levels in milkfish cultured within a typical commercial mariculture setting, we measured ontogenetic (OG) scale cortisol of milkfish sampled from four cage systems (F1-F4) with different geographic locations and management strategies. Sampling stations were located within a mariculture area (approx. 2.2 x 0.6 km) of the Guiguiwanen Channel, Bolinao (Philippines). Each station was sampled twice (time point I and II) with an intermediate time interval of 15 days. According to Aerts et al. (2015), ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) was used to analyze OG scale cortisol.Additional to the stress-physiological data, environmental parameters (oxygen concentration, salinity) were recorded, and the gut content of the fish and the fish feed were analyzed for their carbon (C) and nitrogen (N) content, CN stable isotope signatures, presence of antibiotics (LC-MS/MS), organic matter (pyrolysis-GCMS, MetaboLights accession MTBLS1438), microbial community composition (16S amplicon sequencing, PRJEB33594, OTU table available here), and abundance of the virulence factor gene thermolabile hemolysin of Vibrio sp. (qPCR, primers: tlh-G-vibrio-0515-a-S-22: 5'-GCTGGTTCTTRGGDCAYTTCTC-3', tlh-G-vibrio-0750-a-A-22: 5'-TGGAACGCYACGGTTRTAGTTC-3'). Furthermore, the sampling took place as part of a larger sampling campaign within the ACUTE project (AquaCUlture practice in Tropical coastal Ecosystems: Understanding ecological and socio-economic consequences; funding: Leibniz SAW-2015-ZMT-4), during which also sediment microbial communities and environmental parameters were surveyed (Moncada et al. (2019) doi:10.1093/femsec/fiz006, NCBI Sequence Read Archive (SRA) accession: SRP155505, doi:10.1594/PANGAEA.900758).

title: Fish and invertebrate trawl sampling south of Iceland and in southern Irminger Sea in July 2020

description: This data set has trawl catch weight and biological measurements from the 2nd leg of the Icelandic part of the International Ecosystem Summer Survey in Nordic Seas (IESSNS) conducted in July 2020. The survey area was from the coast, over the shelf edge and into the deep-water basins south of Iceland and in the southern part of the Irminger Sea, defined as IESSNS strata 6, 11 and 12, see embedded map. The survey period was July 11 – 30, 2020, and samples were collected at 27 trawl stations. A specifically designed scientific trawl, called Multpelt832 (ICES 2013a-b, Valdemarsen et al. 2014) with cod-end mesh size of 50 mm, was used at all 27 stations. Trawl depth ranged from surface (trawl headline in surface) to 550 m depth. All trawl catch was identified to lowest possible taxonomic level, total weight of each species recorded, and length and weight of 50 specimen per species measured, or all if less was caught. For blue whiting (Micromesistius poutassou), herring (Clupea harengus), and mackerel (Scomber scombrus) more biological measurements are provided such as sex, maturity, age, and stomach weight. For age determination, the otolith was extracted whole from the specimen at sea and read whole under a dissecting microscope on land by an experienced age reader which is a part of the ICES framework. Gonad maturity stage was visually estimated at sea during sampling by an experienced technician. For taxa Scyphozoa and Natantia decapods only total catch weight per station is recorded. For detailed information about the survey see the survey report (Ólafsdóttir and Kennedy 2020). Various information is provided about the trawling operation and weather. The data is provided by the Marine and Freshwater Research Institute (MFRI) in Iceland.

title: Organic matter and elemental composition of gelatinous and soft-bodied zooplankton in the Northeast Pacific

description: Gelatinous and soft-bodied zooplankton (GZ) have long been considered to have low energetic value and are insufficient to sustain higher trophic levels. However, the nutritional composition of GZ is often poorly known for entire groups, ignoring species-, size- and stage-specific differences. Organic matter and elemental composition (carbon and nitrogen) were measured for more than 1000 specimens from 34 GZ species collected in the Northeast Pacific between 2014-2020 using a variety of nets (CanTrawl250, Bongo net, Juday net, Multinet Medi, Dip net, Midwater trawl, Neuston net). Size-dependent variability was shown for several species. Differences in organic content and elemental composition by development stage were observed in a salp and scyphomedusa species, highlighting the need to consider life cycle stages separately.

title: Fish and invertebrate trawl sampling south and west of Iceland in July 2021

description: This data set has trawl catch weight and biological measurements from the latter half of the Icelandic part of the International Ecosystem Summer Survey in Nordic Seas (IESSNS) conducted in July 2021. The survey area was from the coast and over the shelf edge south and west of Iceland, defined as IESSNS strata 5 and 6, see embedded map. The survey period was July 17 – 26, 2021, and samples were collected at 38 trawl stations. A specifically designed scientific trawl, called Multpelt832 (ICES 2013a-b, Valdemarsen et al. 2014) with cod-end mesh size of 50+ mm, was used at all 38 stations. Trawl depth ranged from surface (trawl headline in surface) at 22 stations and 8 stations was trawling deeper in the water column targeting specific acoustic backscatter with trawl depth of 100 – 400 m. All trawl catch was identified to lowest possible taxonomic level, total weight of each species recorded, and length and weight of 50 specimen per species measured, or all if less was caught. For blue whiting (Micromesistius poutassou), herring (Clupea harengus), and mackerel (Scomber scombrus) more biological measurements are provided such as sex, maturity, age, and stomach weight. For age determination, the otolith or scale was extracted whole from specimen at sea and read whole under a dissecting microscope on land by an experienced age reader part of the ICES framework.
