Day 36: RSV 421 Sailing Northeast of Lagoa dos Patos, Largest Lagoon in South America

On the 36th day of its journey to Antarctica, the Bulgarian military research vessel Sv. Sv. Kiril i Metodii (NAVAL RSV 421) sailed in the Atlantic Ocean some 100 nautical miles northeast of the biggest lagoon in South America, Lagoa dos Patos in Brazil. The lagoon covers an area of over 10,000 sq km south of Porto Alegre, the capital of Brazil’s Rio Grande do Sul state. Leading Seaman Ivan Nedelchev, helmsman of RSV 421, said for BTA that the ship continues to sail at 9 knots, keeping a 220-degree course south-southwest to her second intermediate stop: Mar del Plata in Argentina. The ship is just over 700 miles from the port. BTA Photo/
