Question: What actress stars in Trixie and Breaking the waves?

Context paragraphs:
Surf forecasting: Surf forecasting is the process of using offshore swell data to predict onshore wave conditions.  It is used by millions of people across the world, including professionals who put their forecasts online, meteorologists who work for news crews, and surfers all over the world.  It is impossible to make an exact prediction of the surf (shape and size of breaking waves), but by knowing a few factors a good prediction can be made.  One needs to have an understanding of how waves are formed, a basic knowledge of bathymetry, and information (such as tides, location, and weather) about the surf spot being forecasted to accurately forecast the surf.

Emily Watson: Emily Margaret Watson, OBE (born 14 January 1967) is an English actress.  She was nominated for the Academy Award for Best Actress for her debut film role as Bess McNeil in Lars von Trier's "Breaking the Waves" (1996) and for her role as Jacqueline du Pré in "Hilary and Jackie" (1998), winning the BIFA Award for Best Actress for the latter.  She won the BAFTA TV Award for Best Actress for playing Janet Leach in the 2011 ITV television biopic "Appropriate Adult".

Surf zone: As ocean surface waves come closer to shore they break, forming the foamy, bubbly surface called surf.  The region of breaking waves defines the surf zone.  After breaking in the surf zone, the waves (now reduced in height) continue to move in, and they run up onto the sloping front of the beach, forming an uprush of water called swash.  The water then runs back again as backswash.  The nearshore zone where wave water comes onto the beach is the surf zone.  The water in the surf zone, or breaker zone, is shallow, usually between 5 and 10 m (16 and 33 ft) deep; this causes the waves to be unstable.

Goishi Coast: The Goishi Coast (碁石海岸 , Goishi Kaigan ) is a nationally designated Place of Scenic Beauty and Natural Monument in Ōfunato, Iwate Prefecture, Japan.  The name is derived from the local stones, polished by the waves, that resemble those used in Go.  In 1996 the Ministry of the Environment selected the sound of the waves breaking over Kaminari iwa (雷岩 ) ("lit."  'Thunder Rock') as one of the 100 Soundscapes of Japan.  The Goishi Coast forms part of the Rikuchū Kaigan National Park and is a breeding ground for the black-tailed gull.

Helioseismology: Helioseismology is the process of inferring the internal structure and kinematics of the Sun from the propagation of seismic waves, particularly acoustic waves (p waves) and surface gravity waves (f waves).  It was developed by analogy to geoseismology (originally called simply seismology), and subsequently there emerged asteroseismology, in which seismic waves are analysed to constrain the internal structures of other stars.  Because the Sun is fluid, to a first approximation it cannot support shear waves (s-waves), unlike the seismic waves on Earth.  An exception is the magneto-acoustic waves which appear to be important only in the atmosphere.  The helioseismic waves are generated by the turbulence in the convection zone immediately beneath the Sun's surface.  Certain frequencies are amplified by constructive interference, leading to resonance.  In other words, the turbulence "rings" the sun like a bell.  The resonant waves are reflected near the photosphere, the visible surface of the sun, where they can be observed.  The oscillations are detectable in almost any time series of solar images, but are best observed by measuring the Doppler shift of atmospheric absorption lines.  Details of the propagation of the seismic waves through the Sun, inferred from the resonant frequencies, reveal the Sun's inner structure, allowing astrophysicists to develop an extremely detailed representation of the hydrostatic stratification and the internal angular velocity.  That has permitted the evaluation of the quadrupole moment, formula_1, and higher-order moments of the Sun's external gravitational potential.  It is a more accurate and more robust procedure than trying to infer it from the oblateness of the visible disc.  Together with measurements of the orbits of Mercury and of spacecraft, the result is consistent with General Relativity.

Rip current: A rip current, often referred to simply as a rip, or by the misnomer "rip tide", is a specific kind of water current which can occur near beaches with breaking waves.  However, a rip can often be hard to see and absent from breaking waves, and only recognised by a ripple on the top of the water that heads out to sea.  A rip is a strong, localized, and narrow current of water which moves directly away from the shore, cutting through the lines of breaking waves like a river running out to sea, and is strongest near the surface of the water.

Wave setup: 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 (during the shoaling process).  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.

Skimboarding: Skimboarding (or skimming) is a boardsport in which a "skimboard" (much like a surfboard but smaller and without fins) is used to glide across the water's surface to meet an incoming breaking wave, and ride it back to shore.  Wave-riding skimboarders perform a variety of surface and air maneuvers, at various stages of their ride, out to, and back with, the wave.  Some of these are known as "wraps," "big spins," "360 shove-its" and "180s."  Unlike surfing, skimboarding begins on the beach by dropping the board onto the thin wash of previous waves.  Skimboarders use their momentum to skim out to breaking waves, which they then catch back into shore in a manner similar to surfing.  Another aspect of skimboarding is "flatland," which involves performing tricks derived from skateboarding such as ollies and shove-its on the wash of waves without catching shore breaks. Skimboarding originated in Southern California when Laguna Beach lifeguards wanted to surf the local shore breaks that was too fast and shallow for surfboards.  Skimboarding has developed since then to ride waves much like surfing, performing aerial maneuvers and pulling into the barrel of the wave.  Even further, professionals have started getting towed by waverunners into much larger waves.  Professional Skimboarder, Brad Domke, displayed the new technique in this video.

Gravitational wave background: The gravitational wave background (also GWB and stochastic background) is a possible target of gravitational wave detection experiments.  The detection of such a background would have a profound impact on early-universe cosmology and on high-energy physics.  The emission of gravitational waves from astrophysical sources can create a stochastic background of gravitational waves.  For instance, a sufficiently massive star at the final stage of its evolution will collapse to form either a black hole or a neutron star – in the rapid collapse during the final moments of an explosive supernova event, which can lead to such formations, gravitational waves may theoretically be liberated.  Also, in rapidly rotating neutron stars there is a whole class of instabilities driven by the emission of gravitational waves.

Trixie (film): Trixie is a 2000 American mystery-crime film directed by Alan Rudolph and starring Emily Watson, Nick Nolte, Will Patton and Brittany Murphy.
