Lough Hyne Marine Reserve, West Co. Cork

Introduction

Lough Hyne is a semi-enclosed marine lake situated 3 miles west of Skibereen and some 50 miles from Cork City in Southwest Ireland. It measures just 0.8 km by 0.6 km and it is believed that the Lough was a freshwater lake up to 4000 years ago, when a rise in sea levels joined it with the sea. It is now a highly sheltered, seawater basin connected to the North Atlantic Ocean via a narrow inlet called Barloge Creek.

At the northern end of Barloge Creek, there is a very narrow, shallow constriction known as the “Rapids”. The “Rapids” are no deeper than 5m at high tide and this highly restrictive sill leads to an asymmetrical tide with water flooding in for 4 hours and ebbing for 8.5 hours. Water flow within the Rapids can reach 3ms -1.

Lough Hyne was designated Europe’s first Marine Nature Reserve in 1981 in order to protect the rich biodiversity that occurs within its depths. The Lough supports many different marine habitats and environmental conditions (cliffs, beaches, boulders and saltmarshes in water movement ranging from still to very fast - 0.05 ms -1 to 3ms -1). The deepest part of the Lough is some 52m in the Western Trough. Whilst the rich fauna and flora of Lough Hyne have been protected for over 20 years, scientific research has been ongoing for well over 100 years.

A Brief History of Scientific Research at Lough Hyne

The first recorded biological study at Lough Hyne occurred in 1886 when the Rev. William Spottswood Green made the first recording of the Purple Sea-Urchin Paracentrotus lividus. A species that has become one of the most studied organisms in the Lough and is currently the subject of a long-running population survey by Dr Anne Crook (University of Reading).

The start of more regular biological studies began in 1923, when Prof Louis Renouf from University College Cork began visiting the Lough. In 1928 an ex-army hut was assembled beside the Rapids to act as the first on-site research laboratory. Although being destroyed by tidal surges and reassembled in 1942 and again in 1962, the hut acted as the starting point for regular marine research and led to the construction of two further wooden huts in the 1930’s which attracted the attention of overseas workers.

Among the first visitors to the Lough in the 1930’s were J.A. Kitching and F.J. Ebling. They were regular visitors until the onset of WWII, but the returned in 1946 to begin regular summertime work until 1986. Kitching and Ebling’s team would consist largely of undergraduates camping for the summer in large tents on the southern shore of Lough Hyne.

After visiting Lough Hyne for a number of years Prof. Kitching erected a further two laboratories. A small concrete building on the east side of the Rapids was completed in 1954 and was known as the Dromadoon laboratory. The other was built at Glanafeen on the southern shore of Lough Hyne between 1952 and 1957. This led to the influx of visiting marine biologists especially from the U.K. Unfortunately during the 1960’s the condition of the labs owned by University College Cork deteriorated and were largely unused after 1967. There were few Irish biologists working at the Lough at this time and the remaining buildings beside the Rapids totally collapsed in 1976.

However, in 1975 Dan Minchin from the Irish Department of Agriculture and Fisheries took an interest in the Lough to look at the biology of scallops and their predators using a caravan on the north shore as his lab. This renewed interest led to University College Cork staff and students beginning to conduct research at the Lough once more and in 1987, a new two level building known as the Renouf lab was opened alongside the Rapids (see Figure 2 for picture). At the same time, Prof. Kitching donated his two labs at Glanafeen and Dromadoon to UCC.

The Glanafeen lab was subsequently renamed the Kitching lab in recognition of Prof. Kitching’s services to biological research at Lough Hyne. In December 2001, the Dromadoon laboratory was renamed the John Bohane Laboratory in recognition of the role of John Bohane as Caretaker of Lough Hyne for over 60 years.

Current Research at Lough Hyne

Stefanie Broszeit – Soft sediment ecology of Lough Hyne marine reserve (PhD)
This project focuses on the soft sediment habitat of Lough Hyne which has been studied less frequently than rocky areas. The project has several goals:

  1. To create a list of animals that belong to the soft sediment communities and to see how these communities change during seasons and if they differ in areas of the Lough
  2. How do benthic communities living in the Western Trough cope with the formation of a summer thermocline and associated lack of oxygen – how long does the lack of oxygen prevail and in what manner does recolonisation occur?
  3. To study flow and sedimentation rates in the Lough with a special focus on the Western Trough which is thought to receive large levels of sediments
  4. To study the impact of terrestrial leaf litter input into a marine system

While all this research is carried out in Lough Hyne, knowledge gained may be beneficial to soft sediment ecology in shallow enclosed bays of temperate seas on a more global scale. The project is co-supervised by Dr. Rob McAllen und Prof. John Davenport.

EPA Postdoctoral Fellowship – Dr Mark Jessopp – Nutrient and Ecosystem Dynamics in Ireland’s only Marine Nature Reserve
This project aims to address the nutrient and ecosystem dynamics within Ireland’s only statutory marine reserve with a view to the possible long-term effects of nutrient flux on the rich biodiversity within its depths and in surrounding coastal waters. The project will be the first long term comprehensive analysis of the water quality within Ireland’s only protected marine reserve site and will integrate land use, habitat quality and water management and so influence regional catchment management plans under the Water Framework Directive leading to and impacting on future coastal biodiversity monitoring programmes with a possible view to potential climate change scenarios.

Amy Dale – The community ecology of seagrass beds around Southwest Ireland.
This project will examine the diel, seasonal and inter-annual variation in the community structure of the infaunal and epifaunal macrofauna, inhabiting a variety of seagrass beds in Barloge Creek, Lough Hyne Marine Reserve and at Ventry Bay, Co. Kerry in SW Ireland. The project is co-supervised by Dr Rob McAllen and Dr Pat Whelan. Amy is currently writing up her Thesis.

Sheila McCullagh – Scavenging Biology of Lough Hyne (MSc by research)
This project is using video analysis and potting trials to look at the spatial and temporal abundance of scavenging communities at different areas of Lough Hyne. Co-supervised by Prof. John Davenport and Dr Rob McAllen.

The Department of Zoology, Ecology and Plant Science of University College Cork currently have had a number of PhD students complete their studies at Lough Hyne recently:

Rob Thomas – Recruits in space: supply and patchiness on the seabed.
This project focussed on the recruitment of marine invertebrates at different spatial and temporal scales and examined how the themes of patchiness in larval supply and recruitment, affected the composition and structure of intertidal and shallow sublittoral marine communities. The project was co-supervised by Dr Rob McAllen and Dr David Barnes (British Antarctic Survey, Cambridge). Rob Thomas was awarded his PhD in 2007.

Mark Jessopp – The exchange of larvae between marine reserve and adjacent non-reserve areas. – Part of the MARDEM project partnership.
This project was funded by the HEA North-South Cross Borders initiative in collaboration with Dr Tasman Crowe,.University College Dublin and Dr Mark Johnson, Queen’s University, Belfast. The MARDEM project looked at the way in which marine reserves and SAC’s are designed and monitored. This particular project looked at the exchange of larvae between marine reserves and other adjacent coastal areas to assess the importance of larval transfer and to suggest criteria by which future marine reserves should be designated. The project was supervised by Dr Rob McAllen and Mark Jessopp was awarded his PhD in 2006.


Dougie Watson – Recruitment variability in space and time by benthic invertebrates on Irish Shores.
This study focused on settlement and recruitment on machined slate panels over a monthly time scale.  Five sites were used (two within Lough Hyne) for this portion of the work.  Other studies included comparisons between recruitment to panels and naturally occurring boulder substrata, recruitment differences with regard to orientation of substrata, assemblage structural differences dependant on immersion date and how assemblage structure varied with increasing time of immersion.


Ian Davidson – Using marine benthic migrations to assess biodiversity
The purpose of this research was to investigate intertidal and shallow subtidal epifaunal diversity and assess the influence that small scale (spatial and temporal) migrations has on biodiversity measurement.  In particular, the biodiversity along gradients of substratum, immersion, depth, and flow and determining the relative influence of mobile and sessile taxa in the assemblages was studied.  The study was carried out primarily at Lough Hyne because of the variability in physical conditions in such a small area.  Overall, this study should contribute to a better understanding of community patterns and processes in shallow marine systems.


Kate Rawlinson – Using marine migrations to assess pelagic biodiversity..
This project was an ecological study of the spatial and temporal variation in zooplankton composition and diversity of a semi-isolated community. The study paid particular attention to the influence of environmental parameters on zooplankton vertical migration, and the effect of local and regional factors on community composition and diversity.
