What genre are Clive Cussler novels?

Clive Cussler's novels are considered either adventure or thriller novels. Thrillers tend to rely on the combination of tension and violence, whereas adventure stories focus more on violence.

Cussler's novels, particularly those starring Dirk Pitt, his most famous character, tend to involve a blend of high technology and high adventure. Pitt, who is in many ways modeled after James Bond, engages in a series of often fantastical adventures involving such outlandish plot points as the raising of the shipwreck of the Titanic, the exploration of the long-lost colony of Atlantis and the recovery of ancient caches of South American gold.
