Ver artículoGold Miner is an absolute classic. In the game that dates from the early 2000s, you collect gold, stones, and minerals to reach your daily goal. With the money you collect you can buy upgrades such as explosives, which let you mine more efficiently. The game has been ported to HTML5, which means you can play it both on your desktop and on your browser!
Ver artículoEntrainment rates depend on a number of factors, including depth, dredger type, speed, and strength of suction field. For example, hydraulic dredgers create stronger suction fields than mechanical ones, so are more of a risk to marine life (Reine and Clarke, 1998; Nightingale and Simenstad, 2001). Susceptibility also depends on species.
