The overall responsibility of SciMT is to advise and support the Director of Science on management issues that affect planning and delivery of science on both short and long timescales.
Specific responsibilities of SciMT are:
Chair: Dr Anna Jones, Director of Science

Long-term variability and tendencies in monthly mean semidiurnal tide (12-hr) in zonal (U12) and meridional (V12) winds are investigated in northern polar mesosphere and lower thermosphere (MLT; ∼80–100 km) using…19 March, 2025 by Peter Convey
Lichens play important roles in habitat formation and community succession in polar and alpine ecosystems. Despite their significance, the ecological effects of lichen traits remain poorly researched. We propose a…18 March, 2025 by Hannah Moulton, Lloyd Peck, Peter Convey, Peter Fretwell
Algal blooms play important roles in physical and biological processes on glacial surfaces. Despite this, their occurrence and impacts within an Antarctic context remain understudied. Here, we present evidence of…Read more on Surface darkening by abundant and diverse algae on an Antarctic ice cap
14 March, 2025 by Peter Convey
A major natural route of dispersal to Antarctica is often assumed to be atmospheric transport, although few studies have documented this in detail. Aerial dispersal to Antarctica is very challenging…10 March, 2025 by Peter Convey
Background and Methods: We assessed the prokaryotic and eukaryotic diversity present in non-vegetated and vegetated soils on King George Island, Maritime Antarctic, in combination with measurements of carbon dioxide fluxes.…6 March, 2025 by Peter Convey
In the extreme conditions of Antarctica two native vascular plants are present, Colobanthus quitensis (Kunth) Bartl. (Caryophyllaceae) and Deschampsia antarctica Desv. (Poaceae), distributed along the western Antarctic Peninsula and the…1 March, 2025 by Alistair Crame, Jane Francis
The Cretaceous period is particularly well represented by a thick sequence of clastic sedimentary rocks exposed in the Antarctic Peninsula region of western Antarctica. This was an active margin throughout…Read more on Cretaceous stratigraphy of Antarctica and its global significance
25 February, 2025 by Alison McLaren, Louise Sime, Qinggang Gao
There is an increasing need to understand how water is cycled and transported within the atmosphere to aid water management. Here, atmospheric water tracers are added to the Met Office…Read more on Implementation of Water Tracers in the Met Office Unified Model [EGUsphere preprint]
24 February, 2025 by Peter Convey
Polar ecosystems are threatened by non-native plants, and this risk will increase with climate warming. Non-native plant growth depends on Antarctic environmental conditions and substrates, but these influences are poorly…12 February, 2025 by Andrew Kavanagh, Jade Reidy, Jade Reidy
The mesosphere/lower-thermosphere/ionosphere (MLTI) region is a critical boundary in the coupling of the atmosphere, climate and space weather, however it is one of the least understood regions, making it hard…12 February, 2025 by Peter Convey
The Antarctic midge, Belgica antarctica, is a unique insect endemic to Antarctica. It has a 2-year life cycle, with larvae overwintering in two different instars and adults emerging the following…7 February, 2025 by Louise Sime, Qinggang Gao, Rahul Sivankutty, Xu Zhang
Given relatively abundant paleo-proxies, the study of the last interglacial (LIG, ∼ 129–116 000 years ago, ka) is valuable to understanding the responses and feedback of the Southern Ocean and Antarctica in…6 February, 2025 by Huw Griffiths, Kevin Hughes, Lloyd Peck, Peter Convey
Antarctica harbors many distinctive features of life, yet much about the diversity and functioning of Antarctica’s life remains unknown. Evolutionary histories and functional ecology are well understood only for vertebrates,…2 February, 2025 by Peter Convey
In this study, we evaluated the pathogenic potential of the fungi Aspergillus thermomutatus and Rhodotorula mucilaginosa obtained from maritime Antarctic permafrost using in vivo experiments on immunocompromised BALB/c mice. Despite…1 February, 2025 by Peter Convey
During a 2019 Chilean Antarctic Scientific Expedition (ECA 55) studying crustose coralline algae (CCA) diversity on the Antarctic Peninsula, bleaching of these algae was observed for the first time in…29 January, 2025 by Isobel Rowell, Jack Humby, Louise Sime, Robert Mulvaney
The fate of the West Antarctic Ice Sheet (WAIS) is the largest cause of uncertainty in long-term sea-level projections. In the last interglacial (LIG) around 125,000 years ago, data suggest…Read more on The Ronne Ice Shelf survived the last interglacial
29 January, 2025 by Irene Malmierca Vallet, Louise Sime, Rahul Sivankutty, Sentia Goursaud
The Last Interglacial (LIG) period, approximately 130,000 to 115,000 years ago, represents one of the warmest intervals in the past 800,000 years. Here we simulate water isotopes in precipitation in…28 January, 2025 by Anna Jones, Floortje Van Den Heuvel, Markus Frey, Thomas Lachlan-Cope
In order to reduce the uncertainty of aerosol radiative forcing in global climate models, we need to better understand natural aerosol sources which are important to constrain the current and…27 January, 2025 by Jasmine Lee, Peter Convey
Antarctica is one of Earth's most untouched, inhospitable, and poorly known regions. Although knowledge of its biodiversity has increased over recent decades, a diverse, wide-ranging, and spatially explicit compilation of…Read more on The biodiversity of ice-free Antarctica database [Data paper]
22 January, 2025 by Dominic Hodgson, Kevin Hughes, Peter Convey
Antarctica, Earth’s least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species…
