Modern Nature – Derek Jarman exhibit at the John Hansard Gallery

CDT SIS PGRs and academics started this year with a bit of artistic inspiration.

On the 21st January 2022 we visited the John Hansard Gallery, Southampton City centre to see the Derek Jarman exhibit “Modern Nature” John Hansard Gallery | What’s on | Derek Jarman’s Modern Nature (jhg.art)

Derek Jarman’s Modern Nature draws on Derek Jarman’s extraordinary legacy as a radical artist, filmmaker, writer, gardener, and activist.

The exhibition specifically focuses on his lifelong passion for plants, the human body, the landscape and the greater environment, as evidenced in the living artwork that is Prospect Cottage and its shingle garden in Dungeness, Kent. Created between 1987 and 1994, the house and garden continue Jarman’s legacy into the 21st century as a kind of barometer of the deep past and the near future.

This exhibit considers the relationship between people and the environment.

The PGRs enjoyed the experience of discussing the artwork together and considering themes that touch on their own research areas in a completely different media.

CDT team meals

The CDT SIS students have enjoyed a couple of team meals at local restaurants recently, whilst allowed. We enjoy the time together to meet new students, catch up with friends and celebrate success.

In November we went to the Ancient Viceroy in Portswood for a curry to celebrate Boni Hima and Toshan Rampat passing their vivas and being awarded Engineering Doctorates.

On the 6th December we went to the Brewhouse and Kitchen in Highfield for our Winter Warmer meal. We celebrated a good term and return to the labs for many of the PGRs. This had been a hard term for some but we have made the most of online webinars and opportunities to meet together when possible. We are looking forward to 2022, the final year of research for many of the last cohort and writing up time for earlier cohorts. We hope for success in the research and papers to be published to disseminate our work.

As awareness of the negative externalities created by ports increases, and the perceived local benefits decrease, ports must find new ways to improve the local noneconomic benefits they provide if they are to obtain local support. This global survey collected data from 51 ports in 26 countries. The results highlight a recognition by port authorities that ports face increasing pressure from local residents to reduce their negative impacts and that they should seek to improve the public perception towards the port by increasing local benefits. At present, port information and social media (81%), port events (67%) and education (63%) are the most adopted options. There is a lack of evidence that these measures are effective in improving local perceptions. Maritime museums and public access show a positive association with increasing local awareness of the benefits a port provides, despite their lower levels of adoption (45%). Port centres are the least adopted option at present (29%) and can be expected to increase significantly, with a 43% increase anticipated between numbers of current and expected future centres. Education (14%), public access (13%) and maritime museums (4.5%) also show increases in levels of interest. Maritime museums and public access should be pursued as proven, effective options for improving local perceptions of ports, whilst port centres may provide a new focal point for port-related social and cultural activities.

The response of common carp (Cyprinus carpio) to insonified bubble curtains

The response of common carp (Cyprinus carpio) to insonified bubble curtains

Acoustic bubble curtains have been marketed as relatively low cost and easily maintained behavioural deterrents for fisheries management. Their energy efficiency can be improved by reducing air flow and exploiting bubble resonance. In a series of three flume experiments, we: (1) investigated the reactions of carp to a low air flow bubble curtain, (2) compared the effectiveness of resonant versus non-resonant insonified bubble curtains (for the same volume flux of gas injected through the nozzles) to deter passage, and determined the stimuli responsible for eliciting deterrence, and (3) included the effect of visual cues generated by the bubble curtain. This study showed that bubble curtains with a higher proportion of resonant bubbles deterred carp relatively better. Passage rejection was likely influenced by multiple cues at distances within a body length of the fish— specifically the rate of change in both particle motion and flow velocity caused by rising bubbles. All acoustic bubble curtains were less effective in the presence of daylight, suggesting that vision plays an important role at mediating carp reactions. We discuss the importance of ascertaining the bubble size distribution, in addition to the gas flow rate and aperture size, when characterising acoustically active bubble curtains.

Net Zero Futures 2021 conference

Net-Zero Futures took place at the University of Birmingham on Wednesday 27th October 2021 delivered by the Energy Research Accelerator and the Centre for Postdoctoral Development in Infrastructure, Cities and Energy. Eight CDT Sustainable Infrastructure for Cities and Sustainable Infrastructure Systems postgraduate students and the CDT Manager travelled to this event and two more took part online. This was an opportunity to meet with other researchers interested Energy, Climate change and how we can make a difference.

The event was a unique conference for doctoral and postdoctoral researchers whose work contributes to the Government’s target of Net Zero Carbon emissions by 2050.

Organised by the Energy Research Accelerator (ERA) and the Centre for Postdoctoral Development in Infrastructure, Cities and Energy (C-DICE), this full-day conference at the University of Birmingham includes leading speakers from industry and academia, and provides tailored development sessions.

Go Ape! Team building event

A group of PGRs and staff headed to Go Ape at Itchen Valley Country Park for a team building event on 8th October to welcome new students to CDT Sustainable Infrastructure for Cities.

We completed the Treetop Adventure and some brain teaser games.

Treetop Adventure course included two loops. Loop 1 was made up of confidence building crossings with lots to cling to, where the longer loop 2 had wobbly bridges to test our skills. Both ended with a super zip wire ride back to the ground.

Team games brought out our competitive side. We were asked to work out how to cross a space with planks and piers, pick up blocks with ropes and bungees, and race as teams with planks on our feet. These problem solving exercises challenged us and required us to work together as a whole group or in smaller teams.

Globally, freshwaters are the most degraded and threatened of all ecosystems. In northern temperate regions, beaver reintroductions are increasingly used as a low-cost and self-sustaining means to restore river corridors. River modifications by beavers can increase availability of suitable habitat for fish, including salmonids. This study investigated the response of a population of brown trout to reintroduced beaver habitat modifications in northern Scotland. The field site comprised two streams entering a common loch; one modified by beavers, the other unaltered. Electrofishing and PIT telemetry surveys indicated abundance of post-young of the year (post-YOY) trout was higher in the modified stream. Considering juvenile year groups (YOY and post-YOY) combined, abundance and density varied with year and season. In the modified stream, fork length and mass were greater, there was a greater variety of age classes, and mean growth was positive during all seasons. Beavers had profound effects on the local brown trout population that promoted higher abundances of larger size classes. This study provides important insight into the possible future effect of beavers on freshwater ecosystems.

River Restoration Design

On Thursday 30th September 2021, Dr Daniella Montali-Ashworth gave a presentation to CDT SIS and CDT SICities students online. Daniella was in the first cohort of PGRs for CDT SIS and she graduated in 2019.

She now works as an Ecohydraulic Engineer for Five Rivers – website Five Rivers is a specialist in the consultation, design, delivery and monitoring of ecological and environmental solutions. Daniella favours nature based solutions in her designs and works closely with clients to provide effective river restorations and fish passes.

‘River Restoration Design’.

River restoration is a growing environmental sector with wide ranging benefits for habitat biodiversity, recreation, flood management and landscape development. The talk will cover some of the projects I have delivered over the last few months and the design work required to ensure they are a success.
