Education and career

Beal grew up in the United Kingdom, [1] and was first attracted to aeronautical engineering as an undergraduate at University of Southampton before changing to oceanography. [2] She earned her Ph.D. from the University of Southampton working on the Agulhas Current. [3] Following her Ph.D. she did postdoctoral work at Columbia University and Scripps Institution of Oceanography before moving to the University of Miami in 2003. [1] [4] In 2021 Beal was named editor-in-chief for the Journal of Geophysical Research: Oceans. [5] She formerly served as editor for the ocean section of Geophysical Research Letters from 2014 until 2017. [6] [1]

Research

Beal is known for her work on the Agulhas current, a western boundary current in the southwest Indian Ocean. She first worked on Agulhas Undercurrent [7] and determined the velocity of the current using acoustic measurements. [8] Her work has defined the role of the Agulhas Current in global climate, [9] [10] particularly through her development of high resolution models [11] She has quantified recent widening of the current and its subsequent impact on transport of heat. [12] [13] [14] Her other work in the area includes investigations into monsoons in the Arabian Sea [15] and monitoring climate change in the Indian Ocean using the Indian Ocean Observing System. [16] [17] [18] In Florida, Beal has used cruise ships such as the Explorer of the Seas to examine water currents in the Florida Straits [19] [20] and worked on sea level rise in the area around Miami.

The Agulhas Current is the western boundary current of the southwest Indian Ocean. It flows south along the east coast of Africa from 27°S to 40°S. It is narrow, swift and strong. It is suggested that it is the largest western boundary current in the world ocean, with an estimated net transport of 70 sverdrups, as western boundary currents at comparable latitudes transport less — Brazil Current, Gulf Stream, Kuroshio.

An exopolymer is a biopolymer that is secreted by an organism into the environment. These exopolymers include the biofilms produced by bacteria to anchor them and protect them from environmental conditions. One type of expolymer, Transparent Exopolymers (TEP), found in both marine and aquatic ecosystems, are planktonic acidic polysaccharides of a gel-like consistency, originally defined by their ability to be stained visible by acidic Alcian Blue. Their free-floating characteristic sets TEPs aside from other extracellular polymeric substance subgroups where exopolymers exists as cell coating, dissolved slime or as part of biofilm matrices.

<span class="mw-page-title-main">Sea spray</span> Sea water particles that are formed directly from the ocean

Sea spray are aerosol particles formed from the ocean, mostly by ejection into Earth's atmosphere by bursting bubbles at the air-sea interface. Sea spray contains both organic matter and inorganic salts that form sea salt aerosol (SSA). SSA has the ability to form cloud condensation nuclei (CCN) and remove anthropogenic aerosol pollutants from the atmosphere. Coarse sea spray has also been found to inhibit the development of lightning in storm clouds.

In fluid dynamics, wave setup is the increase in mean water level due to the presence of breaking waves. Similarly, wave setdown is a wave-induced decrease of the mean water level before the waves break. For short, the whole phenomenon is often denoted as wave setup, including both increase and decrease of mean elevation. This setup is primarily present in and near the coastal surf zone. Besides a spatial variation in the (mean) wave setup, also a variation in time may be present – known as surf beat – causing infragravity wave radiation.

<span class="mw-page-title-main">Mode water</span> Type of water mass which is nearly vertically homogeneous

Mode water is defined as a particular type of water mass, which is nearly vertically homogeneous. Its vertical homogeneity is caused by the deep vertical convection in winter. The first term to describe this phenomenon is 18° water, which was used by Valentine Worthington to describe the isothermal layer in the northern Sargasso Sea cool to a temperature of about 18 °C each winter. Then Masuzawa introduced the subtropical mode water concept to describe the thick layer of temperature 16–18 °C in the northwestern North Pacific subtropical gyre, on the southern side of the Kuroshio Extension. The terminology mode water was extended to the thick near-surface layer north of the Subantarctic Front by McCartney, who identified and mapped the properties of the Subantarctic mode water (SAMW). After that, McCartney and Talley then applied the term subpolar mode water (SPMW) to the thick near-surface mixed layers in the North Atlantic’s subpolar gyre.

The Agulhas Return Current (ARC) is an ocean current in the South Indian Ocean. The ARC contributes to the water exchange between oceans by forming a link between the South Atlantic Current and the South Indian Ocean Current. It can reach velocities of up to 4 knots and is therefore popular among participants in trans-oceanic sailing races.

Anne Mee Thompson is an American scientist, who specializes in atmospheric chemistry and climate change.

CICE is a computer model that simulates the growth, melt and movement of sea ice. It has been integrated into many coupled climate system models as well as global ocean and weather forecasting models and is often used as a tool in Arctic and Southern Ocean research. CICE development began in the mid-1990s by the United States Department of Energy (DOE), and it is currently maintained and developed by a group of institutions in North America and Europe known as the CICE Consortium. Its widespread use in earth system science in part owes to the importance of sea ice in determining Earth's planetary albedo, the strength of the global thermohaline circulation in the world's oceans, and in providing surface boundary conditions for atmospheric circulation models, since sea ice occupies a significant proportion (4-6%) of earth's surface. CICE is a type of cryospheric model.

<span class="mw-page-title-main">Cyclonic Niño</span> Climatological phenomenon

Cyclonic Niño is a climatological phenomenon that has been observed in climate models where tropical cyclone activity is increased. Increased tropical cyclone activity mixes ocean waters, introducing cooling in the upper layer of the ocean that quickly dissipates and warming in deeper layers that lasts considerably more, resulting in a net warming of the ocean.

The Agulhas Leakage is an inflow of anomalously warm and saline water from the Indian Ocean into the South Atlantic due to the limited latitudinal extent of the African continent compared to the southern extension of the subtropical super gyre in the Indian Ocean. The process occurs during the retroflection of the Agulhas Current via shedding of anticyclonic Agulhas Rings, cyclonic eddies and direct inflow. The leakage contributes to the Atlantic Meridional Overturning Circulation (AMOC) by supplying its upper limb, which has direct climate implications.

<span class="mw-page-title-main">North Brazil Current Retroflection</span> Ocean current retroflection phenomenon

The North Brazil Current (NBC) retroflects north-eastwards and merges into the North Equatorial Counter Current (NECC). The retroflection occurs in a seasonal pattern when there is strong retroflection from late summer to early winter. There is weakened or no retroflection during other times of the year. Just like in the Agulhas Current, the retroflection also sheds some eddies that make their way to the Caribbean Sea through the Lesser Antilles.
