Heart contractions in CTmax-exposed Pacific herring embryos

These data were collected at Shannon Point Marine Center in Washington, U.S.A. in May, 2021. Embryos were reared at either 10C (ambient) or 16C (heightened) and at either ~500 pCO2 uatm (ambient) or ~2000 pCO2 uatm (heightened). These data measure the cardiovascular response of spring-spawned Pacific herring embryos to critical thermal maximum excursions (CTmax) up to either 20 or 25 celsius for 1, 2, or 3 hours of exposure. Heart contractions assessed cardiac stress in embryos post-CTmax trials. The results evaluate if acute temperature exposure affects the long-term cardiac function of Pacific herring embryos.
