TitleFaunal assemblages from active, declining and buried cold-water coral ecosystems.Associazioni faunistiche collegate agli ecosistemi a coralli di acque fredde attivi, in declino e disattivi.Assemblages de faune provenant d'écosystèmes à coraux d'eau froide actifs, en déclin et ensevelis.Faunen-Vergesellschaftungen von aktiven, rückgängigen und vergrabenen Kaltwasserkorallen-ÖkosystemenIn SintesiLa scoperta di estesi ecosistemi viventi a coralli freddi in oceano aperto ha dato nuove prospettive per la comprensione della loro diversità faunistica e ha fornito la chiave per interpretare la loro evoluzione nel tempo geologico. Il loro studio é essenziale in quanto sono estremenate vulnerabili. Questi ecosistemi rappresentano gli “hot spot” della biodiversità oceanica e sono habitat preferenziale per la riproduzione di molti organismi marini, inclusi pesci commercialmente ricercati.
Lay summary

Soggetto e obiettivo

Questa ricerca porta una nuova visione sullo sviluppo, declino e morte degli ecosistemi a coralli freddi nel Mar Mediterraneo e in Oceano Atlantico negli ultimi 15.000 anni. Gli obiettivi specifici sono: o studio comparativo di ecosistemi viventi e fossili che permette la comprensione dei fattori che favorisco il loro sviluppo e/o ne possono causare il declino e la morte in un contest di cambiamenti globali e antropizzazione. L’analisi  quantitative  della microfauna di questi ecosistemi viventi e fossili paragonata a quella  documentata in zone adiacenti permette di identificare la differenza o similitudine tra ecosistemi fossili e viventi, di evidenziare I fattori ecologici di rischio in previsione della creazioen di parchi naturali.

Abstract

The discovery of extensive provinces of cold-water coral (CWC) carbonate mounds in modern oceans opens new perspectives in our understanding of their diversity and variability as the key to unravel their evolution through time. This research brings new insight on the start-up, development and demise of cold-water carbonate mounds focusing on the key role that CWC ecosystems have played since the last 15-20kyr in the Atlantic Ocean and the Mediterranean. Target regions of this study are (1) the Belgica Mound Province, eastern slope of the Porcupine Seabight (NE Atlantic) where the small-scale Moira Mounds host active CWCs; (2) the declining CWCs recently discovered in the Alboran Sea (The Melilla Mound Field); and (3) the buried CWCs in the Gulf of Cadiz. The Moira Mounds have been target of the FP7-EU Eurofleets cruise of the R/V Belgica (June 2012) granted to the PI. The Alboran Sea and Gulf of Cadiz have been the target of the “Mediterranean Gateway” cruise on the RV Marion Dufresne (June 2013) funded by the EU and partially by the Swiss NSF. The high priority of this research is highlighted by the fact that the European Union granted twice expensive ship time for sampling CWCs and the Irish Government gave the permission to sample within the Irish Special Areas of Conservation (SAC).Sampling was performed by box- and gravity- coring to retrieve sediments, micro- and macro-fauna from at least the last 20 kyr, and by CTD rosette (Conductivity, Temperature, Density) to obtain information about the recent chemical characteristics of the water column.The present project aims at quantitatively investigate biomineralized macro- and micro-fauna, coupled with geochemical analyses (phosphorus content, organic matter, stable isotopes) and dating (by U/Th on corals, AMS14C on foraminifera, isotope stratigraphy and eco-stratigraphy based on relative abundances of planktonic foraminiferal species and/or group with similar ecological significance) to provide highlights on the nucleation and demise of CWCs in the Atlantic and Mediterranean in space and time. Funding is requested to: a) complete the on-going thesis of Claudio Stalder (1 year); b) finalize the micropaleontological and geochemical investigation in the three regions (an additional PhD thesis starting in parallel with the last year of C. Stalder's thesis), and c) open a new field of research topic not present in Swiss Universities such as the macrofauna from CWCs (3 years post-doc position).Our specific objectives are to: characterize CWC habitats of the three sites and analyse the relationships among the key factors triggering CWC development; qualitatively and quantitatively characterize biomineralized macro- and micro-fauna to identify and standardize “Biomineralized Benthic Facies” on- and off-mound to be compared with fossil analogues; characterize the paleo/environmental settings in the three regions and through time and identifiy similarities and differences of modern and fossil CWC from the Atlantic Ocean and the Mediterranean Sea.This project benefits from the collaboration with the members of the ESF-Research Network Programme “COld-Water CArbonate Reservoir systems in Deep Environments” (COCARDE-ERN) funded by ESF from 2011 to 2016 of which the PI is chairperson and the co-applicant is scientific advisors.
