Science Day under the Scientific Groups of the London Convention and London Protocol
The Parties to the London Convention and London Protocol hold a Science Day as part of their Scientific Group meetings each year in an effort to broaden their shared scientific understanding of a topic in a more informal setting. In some cases, a symposium format is adopted where presentations and a summary of proceedings are shared publicly after the session and speakers may be invited that are not otherwise participating in the meeting.
Science Day 2022: Alternative uses of waste
The Contracting Parties to the London Convention and London Protocol have developed Generic and Specific Waste Assessment Guidelines (WAGs), to assist Parties with targeted assessments of each of wastes or other matter that may be considered for disposal at sea. An essential part of the WAGs is the consideration of waste management options, that includes undertaking a comparative risk assessment of the alternatives to disposal at sea.
Therefore in 2021, the governing bodies endorsed "Alternative uses of waste" as a suitable topic for Science Day 2022.
The event was held virtually on the Zoom platform and was attended by 110 participants, plus those who watched via live streaming through IMODOCS. It was presided by the First Vice-Chair of the LC/LP Scientific Groups, Dr. Cristian Mugnai (Italy), assisted by the Second Vice-Chair, Mr. Ulric Van Bloemestein (South Africa).
The Science Day programme included high-level presentations from a range of expert speakers representing applied science, governments, port authorities, and private companies. Those speakers shared experiences gained, research activities, and assessments being undertaken, etc., in relation to alternative uses of waste as they relate to:
beneficial uses of dredged materials including, among others land restoration,
land recreation, use in agriculture or as a building material;
habitat modification and enhancement;
experience on reuse of waste materials in view of circular economy;
legislative barriers/implementation of legislation; and
any other issues related to the alternative management of material listed in annex 1 of the London Protocol (LP).

Science Day 2019 - Practical and achievable monitoring techniques
Monitoring plays an important role in preventing pollution of the marine environment from ocean dumping. It also provides further critical feedback on the effectiveness of individual permit conditions, the evaluation process used in the permitting process, and the management of specific disposal sites. Monitoring is an essential element of the in the Waste Assessment Guidelines and is used in two distinctive ways: compliance monitoring, which verifies that permit conditions were met and; field monitoring, which determines whether assumptions made during the permit review and site selection process were correct and sufficient to protect the environment and human health.
In 2016 and 2017 the IMO published guidance documents providing provide practical information about using low cost and low technology tools that are useful for monitoring of possible environmental impacts associated with disposal at sea and about using low cost and low technology approaches that are useful for monitoring compliance with permit conditions associated with the disposal of waste materials or other matter. These documents represented several years of efforts by the LC/LP Scientific Groups and therefore "Practical and achievable monitoring techniques" was deemed a suitable and relevant topic for Science Day 2019.
It was held as a one-day Science Day symposium which took place on Thursday, 21 March 2019 at the Simon Fraser University Morris J. Wosk Centre for Dialogue in Vancouver, British Columbia, Canada.
Contracting Parties are invited to share experiences, research activities, and assessments being undertaken, etc., in relation to practical and achievable monitoring techniques as they related to:
- The disposal of waste or other matter listed in Annex 1 of the London Protocol (e.g. dredged material, fish waste, organic material, vessels and platforms, etc.);
- Marine litter and microplastics;
- Underwater noise; and
- The application of low cost, low technology field and compliance monitoring guidance.
The Scientific Groups were offered the following presentations:
- "Monitoring in the London Convention/Protocol context and relevant global initiatives", by Linda Porebski, Chair of the Scientific Groups/ Environment and Climate Change Canada;
- "Ocean pollution priorities: where do we start?", Peter S. Ross, Vice-President of Research at Ocean Wise, Vancouver;

Science Day 2018 - Plastics and microplastics in the marine environment including impacts on aquaculture activities
Following the LP/LC governing bodies 2016 statement to encourage action to combat marine litter and to address the increasing global recognition and concern of the issue of plastics and microplastics in the marine environment, this issue was the topic for Science Day 2018. It was held as a one-day symposium on 3 May 2018 at the Maritime Training and Education Center (CIMAR), Valparaíso, Chile, and presided by the First Vice-Chair of the Scientific Groups (Commander Enrique Vargas).
Themes for discussion included:
- International, regional and national initiatives addressing marine litter and microplastics and how these relate to the work of the LC/LP;
- Sources and pathways for plastics to end up in waste streams under the LC/LP (in particular dredged material and sewage sludge) and how can these be controlled;
- Detecting plastics and microplastics in waste streams under the LC/LP;
- Impacts of plastics on aquaculture activities and how these can be addressed; and
- Best practices and experiences in aquaculture activities to manage and reduce marine litter and plastics into the marine environment.
The aim of the symposium was to improve our understanding of plastics and microplastics in the marine environment in relation to the waste streams under the LC/LP and to identify and propose further solutions and actions to address this problem through the LC/LP. The program included a range of speakers from academia, science and government, representing various regions of the world, sharing experiences and scientific knowledge in relation to the different sources and spatial distribution of marine litter, plastics and microplastics in the oceans and their impacts in the marine environment, marine life and resources including the food chain. Presentations also addressed efforts made by some countries to reduce plastic waste and prevent marine litter and microplastic pollution in the marine environment, including environmental policies implemented in relation to regulate the extended producer responsibility for plastics and introduction of bans or taxes for single-use plastic bags.

Science Day 2017 - Waste prevention audits
An integral part of the generic and specific waste assessment guidelines. Waste prevention audits can, and are, used to decrease the amount of waste or pollutants that enter the world’s oceans and so have a paramount importance for the implementation LC/LP.
A waste prevention audit is carried out in order to evaluate: (i) the types, amounts and relative hazard of wastes generated; (ii) waste sources and; (iii) the feasibility of waste reduction and prevention techniques.
Generally, in relation to dredged material, the goal of a waste prevention audit is to identify and control the contamination sources. Contamination of the marine environment can be a consequence of historical and present day inputs both of which can present a problem for the management of estuarine and marine sediments. The presence of plastics and microplastics has been highlighted as a particular concern. Priority should be given to the identification of sources, as well as the reduction and prevention of further contamination of sediments from both point and diffuse sources. A waste prevention strategy is often developed using information gained from a waste prevention audit, and such strategies can provide both short-term and long-term solutions for the identified problems. Successful implementation of waste prevention strategies often requires collaboration among stakeholders and competent authorities with responsibility for the control of contaminant sources.
The Science Day session on "Waste prevention audits" was held on Thursday, 30th March 2017, in IMO headquarters and presided by First and Second Vice-Chairman the Scientific Groups (Commander Enrique Vargas and Dr Andrew Birchenough). The Scientific Groups were offered the following presentations:
- ‘’EPA's Trash Free Waters Program: a Strategic Approach to Reduce Trash in Aquatic Systems’’, by Betsy Valente, United States;
- ‘’Cefas Marine Litter Activities’’, by Thomas Maes, Cefas/United Kingdom;
- ‘’Sources of Micro plastics (Styrofoam buoy)’’, by Gi Hoon-Hong, Republic of Korea;

Science Day 2016 - Environmental management of deep seabed mining
There has been renewed interest in deep-seabed mining (DSM) over the last decade because of the growing demand for metals, the increasingly inaccessible and degraded land-based deposits and advances in technology.
Exploration for the three main types of mineral deposits in international waters is regulated by the International Seabed Authority (ISA) and through national legislation when a proposed mining project is located within the exclusive economic zone or legal continental shelf of a country. DSM has yet to take place in international waters, however exploration is taking place in national waters with deep-sea mining set to begin off the coast of Papua New Guinea in 2018 with the Solwara 1 project.
Much of the focus of DSM is in the South Pacific region and the Deep Sea Minerals Project, a collaboration between the Pacific Community (SPC) and the European Union (EU) is helping Pacific Island countries to improve the governance and management of their deep-sea minerals resources. Therefore, the topic of Science Day “Environmental management of deep seabed mining” was very relevant for the region and we heard from speakers with global, regional and national perspectives including:
How LC/LP fits into deep-seabed mining and associated waste management
Regional Approach in the Pacific
Regional Approach to deep-seabed mining in the Pacific Islands and the Deep Sea Minerals Project
Deep-seabed mining in PnG national waters
Deep-seabed mining in Tongan national waters
Korean Deep-seabed mining programme
Science Day 2015- Marine geoengineering
The Science Day symposium is a regular event and an important agenda item for the joint meetings of Scientific Groups under London Convention and London Protocol. It provides a forum for scientists all over the world to share their points of views on the designated topic related to the remit of London Convention and London Protocol, including its general aim of marine environment protection. Contracting States and interested parties may use it as a resourceful tool to make informed decisions.
The topic of the 2015 Science Day was Marine Geoengineering. According to the 2013 amendment to the London Protocol, Marine geoengineering is defined as of a deliberate intervention in the marine environment to manipulate natural processes, including to counteract anthropogenic climate change and/or its impacts, and that has the potential to result in deleterious effects, especially where those effects may be widespread, long-lasting or severe.
The 2015 Science Day session on "Marine geoengineering" was held on Thursday, 23 April 2015, in IMO headquarters and presided by the First Vice-Chairman of the Scientific Groups, Ms. Linda Porebski (Canada). The symposium was offered the following presentations:
