This

system

is

a

technical

modification

of

the

standard

gravity

corer

assembled

of

square

steel

barrels

(30

x

30

cm)

up

to

6

m

long

and

a

head

weight

of

3t.

A

square

core

catcher

is

attached

to

the

lowest

barrel.

The

kastenlot

is

up

to

12m

long

and

allows

to

recover

large

volumes

of

sediments

in

ocean

regions

where

biogenic

components

occur

in

low

amounts.

To

sample

the

kastenlot

the

square

barrels

must

be

dismantled,

and

a

variable

amount

of

square

plastic

boxes

(up

to

1

m

long)

must

be

pushed

into

the

sediment.
