Seasonal Temperatures and Acidification of sensitive Marine settings: Insight of an uNmatched macro-invertebrate Archive.

Descrizione del progetto

I dati della stagionalità per le previsioni di acidificazione degli oceani

Gli organismi marini sensibili al pH sono sovraffaticati a causa della crescente differenza stagionale di anidride carbonica. L’incremento della temperatura stagionale della superficie marina aggrava la situazione rendendo strumentale la comprensione dei suoi effetti sull’acidificazione degli oceani. Tuttavia non ci sono dati accessibili per la valutazione sul lungo periodo delle dinamiche del pH della temperatura della superficie marina. Il progetto STAMINA, finanziato dall’UE basato sulla formazione mediante ricerca, combinerà la temperatura della superficie marina e il pH per ottenere la prima registrazione di stagionalità per il collasso della tarda era glaciale paleozoica, la quale presenta delle analogie con gli attuali cambiamenti climatici. Il progetto indagherà la stagionalità nei gusci dei moderni brachiopodi, estrarrà le serie stagionali temporali e il pH dai fossili più rilevanti, confronterà serie del passato remoto con serie recenti sul lungo periodo e promuoverà la comprensione al fine di prevedere sfide future.

Obiettivo

The seasonal pCO2 difference has globally increased, implying stronger stress for marine organisms sensitive to pH. This mechanism is reinforced by an overall increase in the seasonal cycle of sea surface temperature (SST), but it would be striking to understand its extent and effect on ocean acidification. Unfortunately, no records exist to evaluate long-term SST-pH dynamics. With this training-through-research project, the Experienced Researcher (ER) will gain the first record of seasonality, coupling SST and pH, for the Late Palaeozoic Ice Age demise, which is analogous to the current climate changes. After calibrating a method to investigate the seasonality in the modern brachiopods’ shells, he will extract seasonal time series of SST and pH from key fossils. Comparing the long term series of the deep past with the recent, the ER will foster the discussion and the understanding about the expected future changes for this chemico-physical system. The employed method will provide a classic model to deal with high resolution paleoenvironmental data using the brachiopods archive, establishing a turning point for the next-generation of scientists, which aim to study deep-past climate variability with high resolution. The University of Cambridge is an outstanding host where the researcher will be included in a high-level team of experts in geosciences. Under the mentor of the supervisor, the ER will gain and transfer relevant knowledge related to population structure and growth of shelled invertebrates, shell morphology, geochemistry and statistics. He will disseminate and communicate the results of his research and he will perform outreach activities to increase the attention of the society about problems concerning climate changes. At the host, he will be involved in training activities aimed to develop transversal and transferrable skills, to complete his formation as scientist, being thus ready for the next stage of his career.
