An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term algae encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. Algal bloom commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest.
The Intergovernmental Oceanographic Commission of UNESCO (IOC/UNESCO) was established by resolution 2.31 adopted by the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO). It first met in Paris at UNESCO Headquarters from 19 to 27 October 1961. Initially, 40 States became members of the commission. The IOC assists governments to address their individual and collective ocean and coastal management needs, through the sharing of knowledge, information and technology as well as through the co-ordination of programs and building capacity in ocean and coastal research, observations and services.
The Natural Environment Research Council (NERC) is a British research council that supports research, training and knowledge transfer activities in the environmental sciences.
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few micrometers (μm) to a few hundred micrometers. Unlike higher plants, microalgae do not have roots, stems, or leaves. They are specially adapted to an environment dominated by viscous forces.
The National Oceanography Centre Southampton (NOCS) is a centre for research, teaching, and technology development in Ocean and Earth science. NOCS was created in 1995 jointly between the University of Southampton and the UK Natural Environment Research Council and is located within the port of Southampton at a purpose-built dockside campus with modern facilities. In 2010 the university and NERC components demerged, and the NERC-managed component became the National Oceanography Centre. The two components of NOCS continue close collaboration through the jointly run Graduate School, shared research facilities and laboratories, complementary research groups, and many joint research grants and publications. The university component “Ocean and Earth Science, National Oceanography Centre Southampton” (OES) is part of the Faculty of Environmental and Life Sciences, (FELS). It was ranked 46th in the world for Earth and Marine Sciences by the QS World University Rankings in 2019.
Oceanic and Atmospheric Research (OAR) is a division of the National Oceanic and Atmospheric Administration (NOAA). OAR is also referred to as NOAA Research.
The National Oceanography Centre (NOC) is a marine science research and technology institution based on two sites in Southampton and Liverpool, England. It is the UK’s largest institution for integrated sea level science, coastal and deep ocean research and technology development. The Centre was established to promote cooperation with institutions across the UK marine science community, to better address key issues including sea level change, the ocean's role is climate change, computer simulation of the ocean's behaviour, and the long term monitoring and future of the Arctic Circle.
The UK Centre for Ecology & Hydrology (UKCEH) is a centre for excellence in environmental science across water, land and air. The organisation has a long history of investigating, monitoring and modelling environmental change. Research topics include: air pollution, biodiversity, chemical risks in the environment, extreme weather events, droughts, floods, greenhouse gas emissions, soil health, sustainable agriculture, sustainable ecosystems, water quality, and water resources management.
Algaculture is a form of aquaculture involving the farming of species of algae.
Algal nutrient solutions are made up of a mixture of chemical salts and seawater. Sometimes referred to as "Growth Media", nutrient solutions, provide the materials needed for algae to grow. Nutrient solutions, as opposed to fertilizers, are designed specifically for use in aquatic environments and their composition is much more precise.In a unified system, algal biomass can be collected by utilizing carbon dioxide emanating from power plants and wastewater discharged by both industrial and domestic sources. This approach allows for the concurrent exploitation of the microalgae's capabilities in both carbon dioxide fixation and wastewater treatment.Algae, macroalgae, and microalgae hold promise in addressing critical global challenges. Sustainable development goals can be advanced through algae-based solutions, to promote a healthy global ecosystem.
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
The Cawthron Institute is New Zealand's largest independent science organisation, specialising in science that supports the environment and development within primary industries. Cawthron has its main facilities in Nelson. It works with regional councils, government departments, major industries, private companies, and other research organisations throughout New Zealand and around the world. Cawthron employs approximately 300 scientists, laboratory technicians, researchers and specialist staff from 26 countries. It has both chemistry and microbiology labs, and has a major focus on food related testing for food safety and export certification. Cawthron holds IANZ accreditation for a wide range of tests. Its scientists include experts in aquaculture, marine and freshwater resources, food safety and quality, algal technologies, biosecurity and analytical testing.
The Scottish Association for Marine Science (SAMS) is one of Europe's leading marine science research organisations, one of the oldest oceanographic organisations in the world and is Scotland's largest and oldest independent marine science organisation.
A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, mechanical damage to other organisms, or by other means. HABs are sometimes defined as only those algal blooms that produce toxins, and sometimes as any algal bloom that can result in severely lower oxygen levels in natural waters, killing organisms in marine or fresh waters. Blooms can last from a few days to many months. After the bloom dies, the microbes that decompose the dead algae use up more of the oxygen, generating a "dead zone" which can cause fish die-offs. When these zones cover a large area for an extended period of time, neither fish nor plants are able to survive. Harmful algal blooms in marine environments are often called "red tides".
The British Oceanographic Data Centre (BODC) is a British national facility responsible for collecting and distributing data about marine environment. BODC is the designated marine science data centre for the United Kingdom and part of the National Oceanography Centre (NOC). Most of its staff work is primarily done at its facility in Liverpool, and a small number work in Southampton. The centre serves as a resource for science, education, industry, and the general public.
Jacqueline Myriam McGlade is a British-born Canadian marine biologist and environmental informatics professor. Her research concerns the spatial and nonlinear dynamics of ecosystems, climate change and scenario development. She is currently professor of resilience and sustainable development at the University College London Institute for Global Prosperity and Faculty of Engineering, UK, and professor at Strathmore University in the Institute for Public Policy and Governance, Kenya.
The Sea Mammal Research Unit (SMRU) is a marine science research organisation in Fife, Scotland. It provides the UK's main science capability in the field of marine mammal biology. It is located at the Gatty Marine Laboratory, part of the University of St Andrews. It was established in 1978, when the Natural Environment Research Council merged its Seals Research Division and Whale Research Unit.
