(2024). Elemental contents of E. superba eggs (carbon, nitrogen, hydrogen) in the context of maternal parasite load (South Georgia, January 2018) (Version 1.0) [Data set]. NERC EDS UK Polar Data Centre. https://doi.org/10.5285/6c4aaf56-1439-4849-b869-8058479e5d6e The quantities of key biologically active elements, carbon, nitrogen, and hydrogen, were measured from batches of eggs from the Antarctic Krill, Euphausia superba. These krill were collected in the "Western Core Box" krill time series region, an area to the north-west of South Georgia, on the RRS James Clark Ross research cruise JR17002 in the summer (January) 2018. Eggs were collected from ship board incubation experiments. Maternal parasite assemblage and load was determined using DNA metabarcoding. Krill with higher loads of apicomplexa and ciliate parasites laid eggs with lower quantities of carbon and nitrogen. These lower quality eggs may have lower survival and recruitment success, suggesting a mechanism by which parasites may influence krill population dynamics.

Eggs were then defrosted, and subsets of 21-54 random eggs were picked by micropipette into pre-weighed tin boats under a dissecting microscope. Eggs were not rinsed, to avoid breakage due to osmotic shock. Eggs were dried at 56 degrees C for 24 hours, weighed on a microbalance, and stored in a desiccator until analysis on an Exeter Analytical Inc. Model CE440 elemental analyser, with standards of Acetanilide (+/-1450 micrograms) included every 10 samples. Data collection: Exeter Analytical Inc. Model CE440 elemental analyser Data quality: Standards of Acetanilide (+/-1450 micrograms) were included every 10 samples. asNeeded completed
