Question: What region was Nikolajs Štelbaums forced to move to during the "Coastal Surf"?

Context paragraphs:
Nikolajs Štelbaums: Nikolajs Štelbaums or Nikolay Shtelbaums (Russian: Николай Штельбаумс ) (13 October 1933 Užava parish, Latvia - 3 April 2008 Omsk, Russia) is a former Soviet speedskater.  As a child he was forced to move to Siberia along with his family in 1949, in connection with the Soviet mass deportation project Operation Priboi of more than 90,000 Estonians, Latvians and Lithuanians.  During his skating career he lived in Omsk, skating for Burevestnik.

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.

Surf City, USA: The title "Surf City, USA" was the subject of a trademark dispute between the California coastal cities of Huntington Beach and Santa Cruz.  Both cities historically claimed the "Surf City" moniker, but the dispute intensified in 2004 after the Huntington Beach Conference and Visitors Bureau successfully filed the "Surf City USA" trademark with the U.S. Patent and Trademark Office.  A settlement was eventually reached in January 2008, which allows Huntington Beach to retain the trademark.

Surf Life Saving Northern Region: Surf Life Saving Northern Region (SLSNR) is the organisation responsible for controlling the surf lifesaving activities around the Auckland region of New Zealand.  It is responsible for surf beaches from Far North Rescue to Raglan Surf Lfe Saving Club.  It is a district organization of Surf Life Saving New Zealand.  Founded in 1933, it currently has 17 affiliated clubs with more than 3000 volunteers.  It currently employs 10 full-time staff and around 70 seasonal professional lifeguards.

Forced displacement: Forced displacement or forced immigration is the coerced movement of a person or persons away from their home or home region and it often connotes violent coercion.  Someone who has experienced forced displacement is a "forced immigrant", a "displaced person" (DP), rarely also a "displacee", or if it is within the same country, an internally displaced person (IDP).  In some cases the forced immigrant can also become a refugee, as that term has a specific legal definition.  A specific form of forced displacement is population transfer, which is a coherent policy to move unwanted persons, for example, as an attempt at ethnic cleansing.  Another form is deportation.

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.

Operation Priboi: Operation Priboi ("Coastal Surf") was the code name for the Soviet mass deportation from the Baltic states on 25–28 March 1949.  The action is also known as the March deportation by Baltic historians.  More than 90,000 Estonians, Latvians and Lithuanians, labeled as enemies of the people, were deported to forced settlements in inhospitable areas of the Soviet Union.  Over 70% of the deportees were women, and children under the age of 16.

Human trafficking in Colombia: The country of Colombia is a major source for women and girls subjected to trafficking in persons, specifically forced prostitution in Latin America, the Caribbean, Western Europe, Asia, and North America, including the United States.  Within Colombia, some men are found in conditions of forced labor, but the forced prostitution of women and children from rural areas and urban areas remains a larger problem.  Individual cases of forced marriage – a risk factor for trafficking – involuntary domestic servitude, and forced begging have been reported.  Some children are subjected to forced labor in mines and quarries, in the agricultural sector or as domestic servants.  Groups at high risk for internal trafficking include displaced persons, poor women in rural areas, and relatives of members of criminal organizations.  Continued armed violence in Colombia has displaced many communities, making them vulnerable to human trafficking.  Guerillas and new illegal armed groups forcibly recruit children to join their ranks; the government estimates thousands of children are exploited under such conditions.  Members of gangs and organized criminal networks force their relatives and acquaintances, and displaced persons – typically women and children – into conditions of forced prostitution and forced labor, including forced work in the illegal drug trade.  Colombia also is a destination for foreign child sex tourists, particularly coastal cities such as Cartagena and Barranquilla.  Migrants from South America, Africa, and China transit Colombia en route to the United States and Europe; some may fall victim to traffickers.

Human trafficking in Gabon: Gabon is primarily a transit country for children from Benin, Nigeria, Togo, Mali, Guinea, and other West African countries who are subjected to human trafficking, specifically forced labor and forced prostitution.  Some victims transit through Gabon en route to exploitation in Equatorial Guinea.  According to UNICEF, the majority of victims are boys who are forced to work as street hawkers or mechanics.  Girls generally are subjected to conditions of involuntary domestic servitude, or forced labor in markets or roadside restaurants.  Stepped-up coastal surveillance over the past year – especially following the October 2009 arrival in Gabonese waters of a sea vessel that was carrying 34 child trafficking victims, some of whom were destined for Equatorial Guinea – caused traffickers to change their routes, which included utilizing estuaries and rivers to transport children.  The majority of victims were young girls, a departure from previous patterns of trafficking in the region.  Trafficking offenders appear to operate in loose ethnic-based crime networks.  Most child traffickers are women, who serve as intermediaries in their countries of origin.  In some cases, child victims report that their parents had turned them over to intermediaries promising employment opportunities in Gabon.  The government has no reports of international organized crime syndicates, employment agencies, marriage brokers, or travel services facilitating trafficking in Gabon.  In 2009, the government began tracking a new trend of young adults between ages 18 and 25 being forced into domestic servitude or prostitution in Gabon.

International Speed Windsurfing Class: The International Speed Windsurfing Class (ISWC) is a class of speed windsurfing boards that has developed over the last 30 years in order to facilitate high performance competition in strong winds and on flat water.  The International Speed Windsurfing Class is controlled by the International Sailing Federation and has been adopted as an international class in spring 2007.  The class is defined as an "experimental" class, which means that the class rules give a wide possibility for the development of new equipment, also outside commonly used technologies.  Speed windsurfing events are normally held on "flat water" as opposed to coastal surf; which means side-offshore wind directions with a strength of at least 20 knots.
