Abstract

"MéTODOS PARA EXTRAçãO DE TESTEMUNHOS DE SONDAGEM POR PISTãO A PARTIR DO LEITO DO MAR" Trata-se de um método para adquirir uma amostra de testemunho de sondagem de material do leito do mar dentro de um tubo de amostragem de extração de testemunho de sondagem possuindo uma extremidade superior, uma extremidade inferior aberta e uma câmara substancialmente cilíndrica se estendendo entre as mesmas, compreendendo as etapas de impulsionar o tubo de amostragem de extração de testemunho de sondagem para dentro do leito do mar e simultaneamente retirar fluído a partir da extremidade superior do tubo de amostragem de extração de testemunho de sondagem em uma taxa suficiente para causar que o material do leito do mar seja arrastado para dentro do tubo de extração de testemunho de sondagem substancialmente na mesma taxa que o tubo de extração de testemunho de sondagem penetra no leito do mar.
